A school band raised $252 by holding a car wash. The band washed 42 cars in all. Which equation can used to find n, the average amount they earned per car?

1 answer

The equation that can be used is:

n = 252/42

This is because the average amount earned per car (n) can be found by dividing the total amount raised ($252) by the number of cars washed (42).

Simplifying this equation gives:

n = 6

Therefore, the average amount earned per car was $6.
