Question

The cost in dollars, y, of a large pizza with x toppings from Pat’s Pizzeria can be modeled by a linear function. A large pizza with no toppings costs $14.00. A large pizza with 2 toppings costs $17.50.

Answer 1

Y = 14
2x + y = 17.5
2x + 14 = 17.5
2x = 3.50
x = 1.75

5x + y = z
5 (1.75) + 14 = z
8.75 + 14 = z
z = $22.75

Answer 2

22.75, that what I got
