Question

Paulo's Pizzeria sells personal pizzas that start at $7 for plain cheese. The pizzeria also offers a variety of toppings, all priced at $2 each.
Write an equation that shows how the price of a personal pizza, y, depends on the number of toppings, x.
Do not include dollar signs in the equation.

Answer 1

The price of a personal pizza, \( y \), can be expressed as a function of the number of toppings, \( x \). Since the base price for a plain cheese pizza is $7 and each additional topping costs $2, the equation can be written as:

\[ y = 7 + 2x \]

This equation shows that the total price \( y \) is equal to the base price of $7 plus $2 for each topping \( x \).
