Pizza Profit and Cost Analysis

The video tutorial explains a rational functions application problem involving a football booster club buying pizzas to sell for profit. The problem is broken down into steps: defining variables, setting up and solving equations, and calculating the original and selling prices of pizzas. The solution involves using a quadratic equation to find the number of pizzas and calculating the cost and selling price per slice. The tutorial emphasizes understanding the problem to avoid mistakes and save time during tests.

What was the initial cost of the pizzas bought by the football booster?

• $1200

• $500

• $900

• $1040

How many slices were there in each pizza?

• 10

• 12

• 8

• 6

What was the total selling price of the pizzas?

• $1200

• $500

• $1040

• $900

If X represents the number of pizzas bought, what is the expression for the cost price per pizza?

• X/1040

• X/900

• 1040/X

• 900/X

What is the profit per slice of pizza?

• $0.75

• $0.25

• $1.00

• $0.50

How many pizzas were kept aside to feed the players?

• 15

• 10

• 20

• 5

What equation represents the profit made from selling the pizzas?

• 1040(X-10) = 900X + 4

• 1040(X-10) = 900X + 4X

• 1040(X-10) = 900X + 4(X-10)

• 1040(X-10) = 900X + 4X^2

What is the common denominator used to solve the equation?

• X

• 10

• X-10

• X(X-10)

What is the value of X, representing the number of pizzas bought?

• 60

• 75

• 100

• 50

What is the original price of each pizza?

• $12

• $20

• $10

• $15
