Question

A group of friends ordered two pizzas, one with pepperoni and one with mushrooms and green peppers. A plain pizza costs 9 dollars. Each extra topping costs 1 dollar. How much did the two pizzas cost?

Answer 1

(9 + 1) + (9 + 2) =

21 dollars

Answer 2

Total cost for two pizzas = 21 dollars

Explanation:

Price of plain pizza = 9 dollars.

Price of topping = 1 dollar

Number of pizzas ordered = 2

Price of pepperoni pizza = 9 + 1 = 10 dollars.

Price of mushroom and pepper pizza = 9 + 2 = 11 dollars.

Total cost of 2 pizzas = 10 + 11 = 21 dollars

Total cost for two pizzas = 21 dollars
