Question

The ESS Ravens bought pizza for $900 to sell at the football game. They kept 10 pizzas 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?​

Answer 1

Answer: 45

Explanation:

The total profit in all was
`1040-900=\$ 140`.

The total profit per pizza was
`(0.50)(8)=\$4`.

This means they sold
`(140)/(4)=35` pizzas.

Adding this to the 10 pizzas held back, there were
`35+10=45` pizzas in the original order.
