Charlie’s Pizza charges $12 for a medium cheese pizza plus $2 for each additional topping. The cost of a medium pizza, y, with x toppings is represented by this equation:

Question

y = 12 + 2x.

Answer 1

To find the cost of a medium pizza with 3 additional toppings, we can substitute x=3 into the equation.

y = 12 + 2(3)
y = 12 + 6
y = 18

Therefore, the cost of a medium pizza with 3 additional toppings would be $18.
