13. For a party, Bob's Pizza charges $12 for each
marusya05 [52]

The number of pizzas you must order for the price to be the same is 5

<h3>How many pizzas must you order for the price to be the same?</h3>

Bob's Pizza charges = $12 for each supreme pizza

This can be represented as

y = 12x

For Mike's Pizzeria, we have

y = 8x + 20

Substitute y = 12x in y = 8x + 20

12x = 8x + 20

Evaluate the like terms

4x = 20

Divide by 4

x = 5

Hence, the number of pizzas you must order for the price to be the same is 5
