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?
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.
To find the average amount the band earned per car, we can set up the equation:
Total amount earned / Total number of cars = Average amount earned per car
In this case, the total amount earned is $252 and the total number of cars washed is 42. Let's substitute these values into the equation:
252 / 42 = n
Simplifying this equation, we get:
6 = n
Therefore, the equation that can be used to find n, the average amount they earned per car, is n = 6.
