Let's represent the number of toppings added as T.
The cost of a large cheese pizza at Peter’s Pizzeria is 6.8 + 0.9T.
The cost of a large cheese pizza at Gavin’s Pizzeria is 7.3 + 0.65T.
To find the number of toppings needed for the pizzas to cost the same, we set the two equations equal to each other:
6.8 + 0.9T = 7.3 + 0.65T
Subtract 0.65T from both sides:
6.8 + 0.25T = 7.3
Subtract 6.8 from both sides:
0.25T = 0.5
Divide both sides by 0.25:
T = 2
Thus, 2 toppings need to be added to a large cheese pizza from Peter’s Pizzeria and Gavin’s Pizzeria to have the same cost. Answer: \boxed{2}.
A large cheese pizza at Peter’s Pizzeria costs $6.80 plus $0.90 for each topping. The cost of a large cheese pizza at Gavin’s Pizzeria is $7.30 plus $0.65 for each topping.
