In order to figure out how many cars she must wash, first you should figure out how much money total you need. This week, she needs $25 for her weekly earnings + $65 for spending money = $90. Then you divide the total amount of money, $90, by 7. The answer is 12.8, but because you can't wash 12.8 cars, the answer is 13.
