Question

A large pizza at Palanzio's Pizza starts at $6.80 with a $0.90 charge per extra topping. A large pizza a Guido's Pizza starts at $7.30 with a $0.65 charge per extra topping. How many toppings will need to be added for the price of the pizzas to be the same?

Answer 1

Palanzio's Pizza: Y= .90x+6.80

Giudo's Pizza: Y= .65x+7.30

.90x + 6.80= .65x + 7.30

.25x + 6.80= 7.30

.25x = .50

x = 2
