Rafael wants to buy a car he needs it down payment of $3000 if he saves $340 each month about how many months will it take him to save the down payment
It will take Rafael 10 months to save the down payment.
Rafael needs down payment of $3000 If he saves $340 each month, to determine how many months it will take him to save the down payment: Further ExplanationMethod:
To solve this question, round out one of the factors to estimate the product
We have:
340 ≈ 300 (we rounded 340 to the nearest hundred)
Let x represent the number of months, then we have:
300 x X = 3000
3 x 100 x X = 3 x 100 times 10 (for better understanding)
X = [tex]\frac{3000}{300}[/tex]
X = 10
so, it will take him about 10 months to save the down payment.
Notably, we rounded 340 to 300 so that it can be easier to use when calculating.

Help please!! A bacteria culture is started with 300 bacteria. After 4 hours, the population had grown to 500 bacteria. If the population grows exponentially. a: write a recursive formula for the number of bacteria. b: write an explicit formula for the number of bacteria. c: if this trend continues, how many bacteria will there be in 1 day?
Answer:
a).[tex]P_{t}=\frac{5}{3}P_{t-1}[/tex]
b).[tex]A_{t}=300e^{0.1277\times t}[/tex]
c). 6429 bacteria
Step-by-step explanation:
Population of the bacteria grows exponentially.
Therefore, growth of the bacteria will be represented by the formula
[tex]P_{t}=P_{0}e^{kt}[/tex]
Where [tex]P_{t}[/tex] = Population of the bacteria after time t
[tex]P_{0}[/tex] = Initial population of the bacteria
k = growth constant
t = time taken for growth
Now we plug in the values in the formula
[tex]P_{t}[/tex] = 500
[tex]P_{0}[/tex] = 300
Time t = 4 hours
[tex]500=300e^{4k}[/tex]
[tex]e^{4k}=\frac{500}{300}[/tex]
Now we take the natural log (ln) on both the sides
[tex]ln(e^{4k})=ln(\frac{500}{300})[/tex]
4k(lne) = ln(500) - ln(300)
4k = 6.2146 - 5.7038
4k = 0.5108
k = [tex]k=\frac{0.5108}{4}=0.1277[/tex]
a). Recursive formula for the sequence formed by the bacterial growth
Since [tex]P_{t}=(1+r)P_{t-1}[/tex]
500 = (1 + r)300
[tex](1+r)=\frac{5}{3}[/tex]
r = [tex]\frac{5}{3}-1=\frac{2}{3}[/tex]
Therefore, the recursive formula will be
[tex]P_{t}=\frac{5}{3}P_{t-1}[/tex]
b). Explicit formula for the number of the bacteria will be
[tex]A_{t}=300e^{0.1277\times t}[/tex]
c). We have to calculate the number of bacteria after 24 hours
[tex]A_{t}=300e^{0.1277\times 24}[/tex]
[tex]A_{t}=300e^{3.0648}[/tex]
[tex]A_{t}=300\times 21.43[/tex]
[tex]A_{t}=6429[/tex] bacteria

Mr. Khans is buying staplers for his office. Each stapler costs $16.99. Write a function to represent the situation.
Answer:
[tex]C(x)=16.99x[/tex]
Step-by-step explanation:
Let x be the number of staplers and C(x) be total cost in dollars of x stapler.
Cost of each stapler = $16.99
So, the formula for total cost is
Total cost = Cost of each units × Number of units
Substitute 16.99 for Cost of each units and x for number of units in the above formula.
Total cost = [tex]16.99\times x[/tex]
Total cost = [tex]16.99x[/tex]
C(x) be total cost in dollars of x stapler. So, the cost function is
[tex]C(x)=16.99x[/tex]
Therefore, the function C(x)=16.99x represents the given situation.
Steve purchases a new car with a down payment and a loan at a 4.9% interest rate. His loan contract is for 60 months and has no prepayment penalties. Steve makes all his payments on time. What should he do if he wants to pay his loan off before 60 months has passed?
make more than the minimum payments
use the down payment to pay down the loan
increase his auto insurance premiums to decrease the amount owed
pay the principal and interest due each month
Answer:
Pay more than the required premiums
Step-by-step explanation:
The loan contract is of for 60 months. If Steve wants to repay the loan before 60 months , he need to pay more than the promised premiums.
In this way , the Steve will have more payment and as there is no prepayment charges, he will not be paying any penalties also. So the extra payment will help him to reduce the borrowed principle and thus thereby reducing the interest charged.
Hence out answer is option one , which says make more than the minimum payments
The difference between two numbers is 30. The
ratio of the bigger number to the smaller number is
7:2. What is the smaller number?
The smaller number of the two numbers that have a difference of 30 and a ratio of 7:2 is 12.
How to find the smaller number?The difference between the two numbers is 30.
The ratio of the bigger number to the smaller number is 7:2.
The smaller number can be calculated as follows;
let
x = bigger number
y = smaller number
Hence, the difference in the numbers is as follows:
x - y = 30
Also, the ratio of the bigger number to the smaller number is 7:2.
The bigger number can be found using the ratio. Recall x + y is the total sum of the numbers.
x = 7 / 9(x + y)
x = 7 / 9x + 7 / 9y
x - 7 / 9x = 7 / 9 y
2 / 9 x = 7 / 9 y
multiply both sides by 9
2x = 7y
The bigger number is 7 / 2 of the smaller number.
x = 7 / 2 y
Therefore, let's substitute the value of x in equation(i).
Recall x - y = 30
7 / 2 y - y = 30
5 / 2 y = 30
cross multiply
5y = 60
y = 60 / 5
y = 12
Hence,
x = 30 + 12
x = 42
Therefore,
smaller number = 12

Step-by-step explanation:
Ricardo is treating his employees and makes the following purchases at the store: 2 packages of bagels at $3.49 each 2 containers of cream cheese at $2.89 each 3 dozen doughnuts at $5.39 each 4 bottles of juice at $3.49 each Ricardo has a business account which saves him 5% on all purchases at this store. The discount is applied before tax. He is charged sales tax of 7%. If Ricardo paid $45.89, then he _____ for his purchase. a. did not pay enough b. paid the correct amount c. paid $2.29 too much d. paid $5.14 too much
Answer:
Ricardo paid $2.29 too much
Step-by-step explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
To begin answering this question we need to calculate the total before applying anything. We calculate this by adding up all the amounts of each item purchased. Like so,
[tex](2*3.49)+(2*2.89)+(3*5.39)+(4*3.49) = Total[/tex]
[tex]6.98+5.78+16.17+13.96 = Total[/tex]
[tex] 42.89= Total[/tex]
Now that we have the total we can apply the 5% discount to this total.
[tex]42.89 * (1-0.05) = 40.75[/tex] ... rounded up
Finally we can apply the 7% sales tax to this purchase to calculate the final price that Ricardo should have paid.
[tex]40.75*(1+0.07) = 43.58[/tex] ... rounded up
As we can see Ricardo paid $2.29 too much

What is the difference between the mean and the median of the data set? {22, 8, 10 ,18 ,12, 20} 0 2 4 6
Answer: The correct option is (A) 0.
Step-by-step explanation: We are given to find the difference between the mean and median of the following data set:
{22, 8, 10 ,18 ,12, 20}.
MEAN: It is the sum of all the values together divided by the number of values in the set.
So, the MEAN of the given data set is
[tex]m=\dfrac{22+8+10+18+12+20}{6}\\\\\\\Rightarrow m=\dfrac{90}{6}\\\\\Rightarrow m=15.[/tex]
MEDIAN: The median of a data set is given by the middle-most value in the data.
If there is an even number of items in the data set, then the median is found by taking the mean of the two middlemost numbers.
Arranging the given data in ascending order, we have
8, 10, 12, 18, 20, 22.
Since there are 6 values, that is even number of values. so the MEDIAN is given by
[tex]M=\dfrac{12+18}{2}\\\\\Rightarrow M=\dfrac{30}{2}\\\\\Rightarrow M=15.[/tex]
Therefore, m = M.
That is, mean and median of the given data are equal.
Hence, the difference is
m - M = 15 - 15 = 0.
Thus, option (A) is CORRECT.
Answer:
Option A - 0
Step-by-step explanation:
Given : Data set {22, 8, 10 ,18 ,12, 20}
To find : What is the difference between the mean and the median of the data set?
Solution :
Data set in increasing order {8, 10 ,12,18, 20,22}
Mean is defined as the division of sum of set values by total number of values.
[tex]M=\frac{\sum x}{n}[/tex]
Substitute the values we get,
[tex]M=\frac{8+10+12+18+20+22}{6}[/tex]
[tex]M=\frac{90}{6}[/tex]
[tex]M=15[/tex]
So, The mean of the set is 15.
Median of even numbers is the average of two middle terms.
[tex]m=\frac{3rd+4th}{2}[/tex]
[tex]m=\frac{12+18}{2}[/tex]
[tex]m=\frac{30}{2}[/tex]
[tex]m=15[/tex]
So, The median of the set is 15.
Now, The difference of the mean and the median of the set is
[tex]d=M-m[/tex]
[tex]d=15-15[/tex]
[tex]d=0[/tex]
Therefore,Option A is correct.
The difference of the mean and the median of the set is 0.
