Pizza Pipers sells personal​ 6-inch pizzas. Below is a partial sample of their menu.

Deluxe.....

​$7.997.99

Sausage....​ $5.99

Mushroom...​ $5.50

Cheese.....​ $4.99

Taking into account that

​$1.001.00

is charged on each additional​ topping, is it a better deal to buy the deluxe pizza or to buy a cheese pizza with 2 additional​ toppings? What is the price per square inch of the better​ deal? (Use 3.14 for

piπ.

The size of a pizza is its​ diameter.)

Answer 1

Cost of a deluxe pizza = $ 7.99

Cost of a Cheese pizza + 2 additional toppings = 4.99 + 1 + 1 = $6.99

Therefore the better deal is to buy the cheese pizza with 2 additional toppings.

________________________

Area of the pizza = r², where r = 3 (r = 1/2 * d, and diameter is 6 inches)

Therefore Area = 3.14 * 3 * 3 = 28.26 square inches

Prize per square inches for the cheese + 2 toppings pizza = 6.99 / 28.26 = 0.247 dollars / square inch
