I think the answer would be 22.75. Since it gives you the price of a pizza with no toppings, then this is your base price. You subtract 14 from 17.50, and then divide the answer by 2 to find out how much each topping costs. (17.50-14 = 3.5 / 2 = 1.75. The function y = 1.75x+14 describes the situation. y = 1.75 (5) + 14 y = 22.75
