Each day that the drama club washes cars to raise money, the club’s only expense is a fixed amount for supplies. If the club charged $12 for each car washed and earned a total profit of $190 in one day by washing 20 cars, how much did the club pay for supplies?

Explanation

Since Profit = Revenue – Expenses, and $12 for a car wash multiplied by 20 car washes = $240:

\(190 = 240 - E\)
\(-50 = -E\)
\($50 = E\)
