Mary buys a dress and a pair of shoes. Before adding the tax she pays $ 48 for the dress which normally sells for $ 62, and she pays $ 34 for the shoes which normally sell for $46.
Answers
a. To find out how much Mary saved, we will have to subtract the sale price from the original price, and then add up the difference to find how much she saved. 62 - 48 is 14. 46 - 34 is 12. 14 + 12 = 26. Mary saved $26 by buying at the sale item price.
b. To find the amount of discount, we can write and solve a proportion, by setting it up like this: change/original = x/100. Change is the distance between two numbers and the original is the previous price. If you know about proportions, you cross multiply the values, and then divide each side by a number to isolate "x". If you solve each proportion correctly, here are your answers for each item:
Dress: ≈ 23% discount
Shoes: ≈ 26% discount
c. Okay. So when we add up the sales prices together, 48 + 34 is 82. In order to find the total amount with tax, we multiply the sale price, by (1 + r). In other words, add 1 to the rate in decimal form and multiply it by the total of the sales price. 82 * 106.5% (1.065) is 87.33. Mary paid a total of $87.33.

Julia has been saving money for a new Tv. The Tv normally costs $340 but is on sale for 30% off. How much money does Julia need to buy the tv?
Answers
You could find 30% of the original value and subtract that from the original value:
340*0.3=102
340-102=238
OR
You can multiply the original cost by 70% (100%-30%)
340*0.7=238
But either way the amount Julia will need to pay is $238

As Mars revolves around the sun, it travels at a speed of approximately
15
miles per second. Convert this speed to miles per minute. At this speed, how many miles will Mars travel in
4
minutes? Do not round your answers.
Answers
Step 2: Now multiply 900 by 4 and that equals 3,600
So, Mars revolves around the sun 900 miles per minute. In four minutes mars would have traveled 3,600 miles every 4 minutes.
Final answer:
To convert Mars' speed from 15 miles per second to miles per minute, multiply by 60 to get 900 miles per minute. Multiplying this by 4 gives the distance Mars will travel in 4 minutes, which is 3600 miles.
Explanation:
As Mars revolves around the sun, it travels at a speed of approximately 15 miles per second. To convert this speed to miles per minute, you simply multiply by the number of seconds in a minute:
15 miles/second × 60 seconds/minute = 900 miles per minute.
At this speed, to find out how many miles Mars will travel in 4 minutes, you multiply Mars' speed in miles per minute by the number of minutes:
900 miles/minute × 4 minutes = 3600 miles.
Therefore, Mars will travel 3600 miles in 4 minutes at the speed of 15 miles per second.

A computer sells for $430 which is 75% reduction of the original price. What is the original price of the computer?
Answers
430 / 75 = 5.733333...
Multiply that answer by 100 to get the original price.
5.73333... x 100 = 573.3333...
That will be your answer.
To double check your work, you can multiply 573.333... by 75 to see if the number in the problem (which was 75% of the original price) matches.
573.3333... x 75 = 430.

Daniel's basic cell phone rate each month is $29.95. Add to that $5.95 for voice mail and $2.95 for text messaging. This past month Daniel spent an additional C dollars on long distance. His total bill was $62.35. How much did Daniel spend on long distance?
Answers
8.9 + 29.95 = 38.85
62.35 - 38.85 = 23.5
So Daniel spent $23.50 on long distance calling
Answer: Daniel spent $23.5 on long distance
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given.
So, Daniel's total bill (62.35) is equal to the sum of the cost of all the services: Basic cell phone rate (29.95); voice mail (5.95); text messaging (2.95); long distance (C)
Mathematically speaking:
29.95+5.95+2.95+C = 62.35
Solving for C
38.85+C =62.35
C =62.35-38.85
C =$23.5
Daniel spent $23.5 on long distance
What is the first step you will use to solve this equation:
4x +2 = 7x - 13
Add 7x to both sides
Add 13 to both sides
Subtract 4x from both sides
Subtract 2 from both sides
Answers
4x +2 = 7x - 13 would then simplify to
3x - 13 = 2 ( you can switch the problem around as long as you dont switch the variables around )
then you have to + 13 which simplifies to
3x = 15
then you divide by 3 which equals
x=5

Why do u think rates are usually written as unit rates
Answers
The rate usually written for the amount of things is changing in one unit.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
A rate in mathematics is the comparison of two related values expressed in different units. The numerator of the ratio indicates the rate of change in the other (dependent) factor if the base of the ratio is written as a cohesive block of one of these variables, and if it is assumed that this quantity may be modified systematically (i.e., is an independent variable).
The rate usually written for the amount of units anything in one unit of something.

On the first day of the year, you have $700 in your bank account. You spend $35 per week. Your friend starts the year with $450 in his bank account. He saves $15 per week.
Solve the equation 700 – 35w = 450 + 15w to find out how many weeks, w, it will take for you and your friend have the same amount of money in your accounts.
Answers
First we should put all the w's on one side and regular numbers on the other, so:
250 = 50w
If we divide by 50 on both sides, we get:
w = 5
It will take 5 weeks for you and your friend to have the same amount of money in your back accounts.
