The 8th grade class had a fundraiser for a ckasspriject. The class set a goal to raise $300. They charge $5.00 for each car they washed. They have collected 65% of their goal so far. How many more cars must they wash to reach the goal
First we need to find out how many cars they have to wash in total. To do that we need to divide 300 by 5. 300÷5 = 60. Since we know that they've collected 65% of their goal, we need to find 65% of 60. 65% of 60 = 39. Now we know that they've already washed 39 cars, so we need to subtract 39 from their entire goal of 60 cars. 60-39 = 21 cars.
