Alonso can't decide which size pizza to order. The 10-inch cheese and sausage pizza is $7.99, while the 12-inch deluxe is $8.99. The dimensions given are the diameters of the pizzas. If he gets the 10-inch pizza, the total price will be divided among 3 people. If he chooses the 12-inch pizza, then the total price will be divided among 4 people. Which is the better buy? How much will each person pay?
The area of the 10-inch pizza is:
A = 3.14 * 25
The area of the 12-inch pizza is:
A = 3.14 * 36
I think you can do the rest of the math.
