Alonso can't decide which size pizza to order. The 10inch cheese and sausage pizza is $7.99, while
the 12inch deluxe is $8.99. The dimensions given are the diameters of the pizzas. If he gets the
10inch pizza, the total price will be divided among 3 people. If he chooses the 12inch pizza, then
the total price will be divided among 4 people. Which is the better buy? How much will each
person pay?

total area of the pizza= ðR2
Cheese + Sausage: 25ð
Deluxe: 36ð
$7.99/3 people = $2.66 for 8.33ð sq in.
$8.99/4 people = $2.24 for 9ð sq in.
The deluxe pizza is the better buy because you pay less per person
