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.

Question

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, \( x \). Starting with the base price of the pizza and adding the cost of the toppings, the equation can be written as:

\[ y = 7 + 2x \]

Here, \( 7 \) represents the price of the plain cheese pizza, and \( 2x \) represents the total cost of the \( x \) number of toppings, each priced at $2.
