12 cars

7 vans

Explanation:

This is right.

Answer 2

The car wash washed 11 cars and 8 vans.

To solve this problem, we can use a system of equations.

Let x be the number of cars washed and y be the number of vans washed.

We know that there were 19 total vehicles washed, so x + y = 19.

We also know that $64 was collected, so 3x + 4y = 64. Solving for x and y gives us x = 11 and y = 8
