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?
To determine which pizza is the better buy and calculate how much each person will pay, we need to compare the price per person for both options.
Let's start with the 10-inch cheese and sausage pizza. It costs $7.99, and the total price will be divided among 3 people. To find out how much each person will pay, we can divide the total price by the number of people: $7.99 / 3 = $2.66 (rounded to the nearest cent).
Now, let's consider the 12-inch deluxe pizza. It costs $8.99, and the total price will be divided among 4 people. To calculate how much each person will pay, we divide the total price by the number of people: $8.99 / 4 = $2.2475. However, we should be dividing the total price evenly among the 4 people, so we round this value up to the nearest cent. Thus, each person will pay $2.25.
Comparing the prices per person, we find that for the 10-inch pizza, each person pays $2.66, while for the 12-inch pizza, each person pays $2.25.
Therefore, the 12-inch deluxe pizza is the better buy in terms of price per person, as it is cheaper at $2.25 compared to $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.
