Question

if you want to buy a cd player for $119.99 in 8 weeks, and you earn $15 a week, what percent of your weekly earnings will you need to save?

Answer 1

First what is the total amount of money you are going to make in 8 weeks, knowing you make 15 dollars per week?

Answer 2

120$

Answer 3

Percent just means out of 100

so you have a total of 120 dollars and the cd player costs 119.99 dollars

so you take the ratio to see how many times 120 goes into 119.99 to figure out the ratio, this will give you a decimal. Multiplying by 100 will convert it to percent, percent is really just used because people like to look at whole numbers rather than decimals.

Answer 4

so it is like a test, the test has 10 questions and you get 5 right

5/10 = 0.5
0.5 * 100 = 50%
