From the information provided, you know that the profit would be equal to the price per car for the number of cars washed minus the amount you spent on supplies, which would be:
P=6x-15, where:
P is the profit
x is the amount of cars washed
Also, you know that the profit is 93, so you can replace P in the formula and solve for x:

108=6x
x=18
According to this, the answer is that you and your friends washed 18 cars.
