Question 10 • Algebra I

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 large pizza with 5 toppings? Round to the nearest penny.

Answer
A
19 dollars
B
43 dollars and 75 cents
C
22 dollars and 75 cents
D
70 dollars

Explanation

With 2 toppings, the price increases by $17.50 − $14.00 = $3.50, so each topping adds $3.50 ÷ 2 = $1.75. For 5 toppings, the cost is $14.00 + 5($1.75) = $22.75. The correct choice is 22 dollars and 75 cents.
