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.

What is the cost of a pizza with 5 toppings? Round to the nearest penny.

Answer 1

22.75 is the answer I think

Answer 2

y = 14 + 1.75x

with 5 toppings...
y = 14 + 1.75(5)
y = 14 + 8.75
y = 22.75 <===
