You are planning to buy one of two brands of sofas, which you hope to use over the next twenty years. Brand J costs $975 and lasts for about twenty years. Brand K costs $265 and lasts for about five years, so you will need to buy four Brand K sofas to equal one Brand J sofa. In either case, you plan to pay for your sofa using your credit card, which has an interest rate of 14.55%, compounded monthly. You can pay off a Brand J sofa with eight years of monthly payments, and you can pay off a Brand K sofa with three years of monthly payments. Assuming that you make no other purchases on your credit card, over twenty years, which brand will be cheaper, and how much cheaper will it be? (Round all dollar values to the nearest cent.) a. Brand J will be $591.36 cheaper than Brand K. b. Brand J will be $85.00 cheaper than Brand K. c. Brand K will be $1,132.23 cheaper than Brand J. d. Brand K will be $340.32 cheaper than Brand J.

The loan amount is calculated by amortization and Brand K will be $340.32 cheaper than Brand J
What is Amortization?Loan amortisation is the practise of making recurrent payments over time to completely pay off the principal and interest on a loan.
Mortgage amortisation is a word used in finance to describe the process of paying down your mortgage. The mortgage lender establishes a payment plan for you when you take out a mortgage. This uncomplicated plan, which includes equal payments over the course of your loan if you have a fixed-rate mortgage, is easy to understand.
The amount is calculated using the amortization formula:
P = a ÷ {{[(1 + r/n)^nt] - 1} ÷ [r/n(1 + r/n)^nt]}
where:
P is monthly payment
a is credit amount
r is the interest rate
t is the time in years
n is number of times the interest is compounded
Given data ,
Let the total loan amount for the brand J be represented as J
a = $975
r = 14.55% = 0.1455
t = 8 years
n = 12
Now , the amortization formula is
P = a ÷ {{[(1 + r/n)^nt] - 1} ÷ [r/n(1 + r/n)^nt]}
P = 975 ÷ {{[(1 + 0.1455/12)^12×8] - 1} ÷ [0.1455/12(1 + 0.1455/12)^12×8]}
P = $17.24
Total amount paid J = $17.24 × 96 = $1655.04
Let the total loan amount for the brand K be represented as K
a = $265
r = 14.55% = 0.1455
t = 3 years
n = 12
Now , the amortization formula is
P = a ÷ {{[(1 + r/n)^nt] - 1} ÷ [r/n(1 + r/n)^nt]}
P = 265 ÷ {{[(1 + 0.1455/12)^12×3] - 1} ÷ [0.1455/12(1 + 0.1455/12)^12×3]}
P = $9.13
Total amount paid K = $9.13 × 12 × 3 × 4 = $1314.72
The difference of amount of sofa j and sofa k = D
D = J - K
D = $1 655.04 - $ 1314.72 = $ 340.32
Hence , Brand K will be cheaper than Brand J by $340.32

Answers
To find the cost per can when buying 3 packages of cans, multiply the cost of a single package by 3 to get the total cost, then divide the total cost by the total number of cans to find the cost per can.
To find the cost per can when buying 3 packages of 10 cans each:
Cost of 1 package with 10 cans = $14Cost of 3 packages = 3 x $14 = $42Number of cans = 3 packages x 10 cans per package = 30 cansCost per can = Total cost / Number of cans = $42 / 30 cans = $1.40kelly puts $350 in a savings account. The savings account accrues interest at a flat rate of 1.05% a month. How much will it count be worth in 7 months?

now, if we nevermind "t" as years and just use it as an interest cycle, then we can say the rate is 1.05% and the period is 7 cycles.
[tex]\bf \qquad \textit{Simple Interest Earned Amount}\\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\to& \$350\\ r=rate\to 1.05\%\to \frac{1.05}{100}\to &0.0105\\ t=cycles \to 7 \end{cases} \\\\\\ A=350(1+0.0105\cdot 7)[/tex]
The "a" will represent your initial value, the value that you are already given in the problem, in this case, it is $350. The "b" will be your growth/decay factor, in this case is 1.05%. However, it cannot stay a percent, but must be changed into a decimal. For this factor in particular, since there's a decimal already included, you'd move the decimal two places to the left, giving you 0.0105.
Since the factor is more than 1, you'd add the decimal by one, giving you 1.0105. Now, the "x" represents the amount of time. In this case, it would be 7 months. Let's set up the equation:
y = 350(1.0105)^7 = 376.5 (377 if rounded). In 7 months, Kelly will have $376.5.
Solve x2 – 8x = 20 by completing the square. Which is the solution set of the equation? {–22, 14} {–14, 22} {–10, 2} {–2, 10}
Answers
Answer: D is the right answer. The solution set of the given equation={-2,10}.
Explanation:
Given equation: [tex]x^2-8x=20[/tex]
The standard perfect square trinomial equation is [tex]x^2+2ax+a^2=(x+a)^2[/tex]
On comparing this with the left side of the given equation ,we get 2a=-8
⇒a= -4 and [tex]a^2=16[/tex]
Now to make given equation perfect square add 16 on the both sides, we get [tex]x^2-8x+16=20+16\\\Rightarrow(x-4)^2=36[/tex]
Taking square root on both the sides we get,
[tex]x-4=-6\ or\ x-4=6[/tex]
add 4 on both sides, we get
⇒x= -6+4 or x=6+4
⇒x=-2 or x=10
Therefore, the solution set of the given equation={-2,10}.
Thus D is the right answer.

If the local hospital has decided to follow the 1:4 nurse-to-patient ratio, how many patients can they treat if they have 120 nurses?
Answers
Final answer:
The local hospital can treat a maximum of 480 patients if they follow the 1:4 nurse-to-patient ratio and have 120 nurses.
Explanation:
The local hospital can treat a maximum of 480 patients if they follow the 1:4 nurse-to-patient ratio and have 120 nurses.
To calculate the maximum number of patients the hospital can treat, we divide the number of nurses by the nurse-to-patient ratio. In this case, the ratio is 1:4, so for every 1 nurse, there are 4 patients. Therefore, each nurse can handle 4 patients.
To find the maximum number of patients, we multiply the number of nurses by the number of patients each nurse can handle. In this case, 120 nurses multiplied by 4 patients per nurse equals 480 patients.

logan made a treasure hunt map.the treasure is 25cm away from his location.if each 1cm on the scale drawing equals 5 meters, then how far he is from treasure?
Answers
125 meters is the answer
Logan's treasure is represented as 25 cm away on his map; using the scale of 1 cm to 5 meters, it can be calculated that he is 125 meters away from the treasure by multiplying the map distance by the scale factor.
Logan has created a treasure hunt map where the scale indicates that 1 cm on the map corresponds to an actual distance of 5 meters. To determine the actual distance Logan is from the treasure, we first note that the treasure is shown as 25 cm away from his location on the map. Since the scale factor is 1 cm to 5 meters, we can set up a simple multiplication to find the actual distance.
The calculation would be as follows:
Scale factor: 1 cm = 5 meters
Map distance: 25 cm
Actual distance: 25 cm x 5 meters/cm
By multiplying the map distance by the scale factor, we get:
Actual distance = 25 x 5 = 125 meters
Therefore, Logan is 125 meters away from the treasure.

Answer:
Option C. $125.25
Step-by-step explanation:
Jeremy is shopping online for skating equipment.
The price of long board with trucks and wheels = $146.25
Jeremy gets a discount on his purchase = $21.00
the final amount that Jeremy would be billed.
We subtract the discount from the price of item.
= $146.25 - $21.00 = $125.25
The final amount that Jeremy would be billed is $125.25.

To solve the equation 10 - 6x - 9x^2 = -9x, we'll use the quadratic formula. The solutions for x are (3 + √369)/18 and (3 - √369)/18.
Explanation:To solve the equation 10 - 6x - 9x2 = -9x, we'll start by bringing all the terms to one side of the equation to set it equal to zero. Rearranging the equation, we get 9x2 - 3x - 10 = 0. We can then use factoring, the quadratic formula, or completing the square to solve for x. In this case, let's use the quadratic formula.
The quadratic formula states:
x = (-b ± √(b2 - 4ac))/(2a)
Using the values from our equation, we have:
x = (-(-3) ± √((-3)2 - 4(9)(-10)))/(2(9))
Simplifying further, we have:
x = (3 ± √(9 + 360))/18
x = (3 ± √369)/18
