Answer 2

In this question, it is given that :

The total amount of money M earned by washing cars at the school fundraiser is proportional to the number of cars , c , washed at the constant Price ,p .

That is , for number of cars,1, we will get

`M = p`

For number of cars,2, we will get

`M = 2p`

For number of cars,3, we will get

`M= 3 p`

Therefore for number of cars,c , we will get

`M = cp`

Correct option is D .
