Answer + Explanation:
Let x be the number of additional toppings on the medium cheese pizza.
The cost of the medium cheese pizza is $8.50, and the cost of each additional topping is $0.75.
Therefore, the equation for the total cost of a medium pizza with x additional toppings is:
Total Cost = $8.50 + ($0.75 x)
To find the cost of a medium pizza with, for example, 3 additional toppings, we would substitute 3 for x in the equation and simplify:
Total Cost = $8.50 + ($0.75 x 3)
Total Cost = $8.50 + $2.25
Total Cost = $10.75
So the cost of a medium pizza with 3 additional toppings would be $10.75.
