Raul calculated that he would spend $125 on school supplies this year. He actually spent $87.50 on school supplies. What is Raul’s percent of error?
Raul spent less than he'd anticipated spending. To learn how much less, subtract $87.50 from the $125 budget figure. This "difference" is negative.
Next, divide this "difference" by $125. The correct result will be a negative decimal fraction. You must multiply this result by 100% to convert it to a percentage, as required.
