Question

Tim sells two types of pizza. He charges $10 for a cheese pizza and $15 for a pepperoni pizza. Yesterday he sold 64 pizzas in all. For every cheese pizza, he sells 3 pepperoni pizzas. How much money did he make selling pizzas yesterday?

Answer 1

Tim sells three pepperoni pizzas for every one cheese pizza. this means he sells three times the amount of pepperoni compared to cheese

x = # cheese pizzas

x*3 = # pepperoni pizzas

x + 3x = 64
4x = 64
x = 16 cheese pizzas

64 - 16 = 48 pepperoni pizzas

he sells 16 cheese pizzas and 48 pepperoni pizzas

price of cheese: $10
price of pepperoni: $15

10(16) + 15(48) = 160 + 720 = $880

hope this helps
