Answer:
20x+25y
Step-by-step explanation:
First, let's solve for the cars. For one car, a wash and a wax would cost $20, but instead, we're solving for X cars. so instead of 1(20), we would have x(20), which we can simplify to 20x. Now for the trucks, we're going to add the 10 and the 15, which is 25, for one car, and 25y for Y cars.
