2. the proceeds from a car wash are directly proportional to the number of cars washed. the total after 9 cars was $180. a. how much can be raised if 60 cars are washed? $ (do not add a comma.) b. if $1,500 was earned from the car wash, how many cars were washed? cars

Answer

Explanation:

Step1: Find the amount per car

Since the proceeds are directly proportional, we find the amount per car. The amount per car when 9 cars are washed and the total is $180 is $\frac{180}{9}=20$ dollars per car.

Step2: Calculate amount for 60 cars

If each car brings in $20, for 60 cars, the total amount raised is $20\times60 = 1200$ dollars.

Step3: Calculate number of cars for $1500

If each car brings in $20 and the total earned is $1500, the number of cars washed is $\frac{1500}{20}=75$ cars.

Answer:

A. 1200 B. 75
