You are ordering pizzas for a birthday party and getting them delivered to your house. You order 1 pepperoni pizzas, 8 cheese pizzas, and 4 Hawaiian pizzas. There is a delivery fee of $5.50. If your total comes to $184.54, how much was each pizza? Assume that all types of pizza cost the same amount.

Answer 1

Let's say the cost of each pizza is x.
The cost of 1 pepperoni pizza is x.
The cost of 8 cheese pizzas is 8x.
The cost of 4 Hawaiian pizzas is 4x.
The total cost of the pizzas is x + 8x + 4x = 13x.
Including the delivery fee, the total cost is 13x + 5.50 = 184.54.
13x = 184.54 - 5.50 = 179.04
The cost of each pizza is x = 179.04/13 = $<<179.04/13=13.77>>13.77. Answer: \boxed{13.77}.
