Rachel decided to save 15 percent of the money she earned. In one month she earned $1,584. How much money did she save?

Answer 1

We know that Rachel earned $1,584 and wants to save 15% of that amount. Whenever you see a percentage followed by the word "of," this means we are dealing with multiplication.

So, you need to multiply 15% by $1,584. Whenever you are multiplying a percent, you must turn it into a decimal, in which you have to move two decimal places to the left starting at the end of the number. So, 15% is 0.15. Now, you just multiply: 0.15 x 1,584. This will give you an answer of 237.6. Since we are dealing with money, there should be two numbers after the decimal, since cents are always displayed with two digits. So, the answer should be 237.60, but make sure to add the money sign, $237.60.

Rachel saved $237.60.
