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 12 inch pizza should be bought
each person pays about $2.24
To determine which pizza is the better buy, we need to calculate the price per person for each option.
For the 10-inch pizza, the total price is $7.99, and it needs to be divided among 3 people. To find the price per person, divide the total price by the number of people:
Price per person for the 10-inch pizza = $7.99 / 3 = $2.66 per person
For the 12-inch pizza, the total price is $8.99, and it needs to be divided among 4 people. To find the price per person, divide the total price by the number of people:
Price per person for the 12-inch pizza = $8.99 / 4 = $2.24 per person
Comparing the price per person for each option, we see that the 12-inch pizza is the better buy. Each person will pay $2.24 for the 12-inch pizza, while each person will pay $2.66 for the 10-inch pizza.
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.
