The football boosters bought pizza for $900 to sell at the game. They kept 10 pizza to feed the players after the game and sold the rest for $1040. There were 8 slices in each pizza. Their profit was 50 cents a slice.

A) how many pizzas were in the original order.
B) What was the original price of each pizza? C) What did they charge per slice?
D) if they bought plain cheese pizza, the original price would be $10 per pizza. What would this make their profit per slice if they sold it for the same price as before and still saved 10 pizzas for the players?

A) The football boosters sold 30 pizzas at the game. They kept 10 for the players, so the original order had a total of 40 pizzas.

B) The original price of each pizza can be calculated by dividing the total amount spent on the pizzas ($900) by the total number of pizzas (40). $900/40 = $22.50 per pizza.
C) To find out what they charged per slice, we first need to determine the total revenue from selling the pizzas. They sold 30 pizzas for $1040. This means each pizza was sold for $1040/30 = $34.67. Since each pizza has 8 slices, the price per slice was $34.67/8 = $4.33.
D) If the boosters bought plain cheese pizza for $10 per pizza, their profit per pizza would be $34.67 - $10 = $24.67. Since each pizza has 8 slices, this would make their profit per slice $24.67/8 = $3.08.
