Answer:

$880

Step-by-step explanation:

This is called a system of equations!! Here's how to do it:

1. Make Equations

In this case, the equations would be

  • p+c=64 (this is saying that pepperoni pizzas plus cheese pizzas equal 64, which we got from the question.)
  • 1/3c=p (this is telling us that he sells 1 pepperonis for 1/3 cheese pizza)

2. Solve the system of equations

For this problem, we will substitute 1/3c for p. The problem becomes

  • 4/3c = 64

Then you divide by 4/3 to get p by itself:

  • p=48

Now substitute 48 for p in the first equation.

  • c=16

3. Find the money amounts

Now that you know that pepperoni pizzas equal 48, and cheese equals 16, this is easy.

  • Multiply 16*10 to get the cheese cost. ($160)
  • Multiply 15*48 to get the pepperoni cost ($720)
  • Then add those to get the total!
