Pizza Pricing and Quadratic Equations

Dominique bakes pizzas daily, initially spending $8 on the oven and $1.50 per pizza on ingredients. When ingredient costs rise to $2, she calculates that baking 8 more pizzas daily keeps expenses per pizza constant. The video explains how to set up and solve an equation to find the number of pizzas baked before the price change, using a quadratic equation approach.

What was the daily cost for using the oven before the price change?

• $10

• $8

• $2

• $1.50

What variable is used to represent the number of pizzas baked before the price change?

• y

• x

• p

• z

What is the equation used to find the number of pizzas baked before the price change?

• 8 + 2(p + 8) = 8 + 1.5p

• 8 + 2p = 8 + 1.5(p + 8)

• 8 + 1.5p = 8 + 2p

• 8 + 1.5p = 8 + 2(p + 8)

What type of equation is used to solve for the number of pizzas baked?

• Linear

• Quadratic

• Exponential

• Logarithmic

What is the first step in solving the quadratic equation?

• Add terms

• Subtract terms

• Multiply terms

• Divide terms

What is the correct factorization of the quadratic equation?

• (p + 16)(p - 8)

• (p - 16)(p + 8)

• (p - 8)(p + 16)

• (p + 8)(p - 16)
