Question

Rachel is ordering pizza. Tony’s pizza charges $7 for a large cheese pizza plus $0.75 for each additional topping. Maria’s pizza charges $8 for a large pizza plus $0.50 for each additional topping. For what number of toppings will the cost of a large pizza be the same at either restaurant?

Answer 1

2 toppings at the first restaurant will cost the same as 3 toppings at the second restaurant (both $1.50)

Answer 2

let no. of toppings = x

cost of tony's ppizza = 7 + 0.75x

cost of maria's pizza = 8 + 0.5x

according to question:

8 + .5x = 7+ .75x

=> 0.25x = 1

=> x = 4
