Gina is having a party and wants to spend less than $450. She has already spent $300. The only item left on her list is pizzas, which cost $15 each.
How many pizzas, x, can she purchase and stay under her budget? Select the inequality that includes the largest number of pizzas she can purchase and still stay under her budget.
A.
x < 30
B.
x < 135
C.
x < 20
D.
x < 10
The total amount Gina can spend is $450 - $300 = $150.
Each pizza costs $15, so the inequality to represent the largest number of pizzas she can purchase and still stay under her budget is:
x * $15 < $150
Solving for x:
x < $150 / $15
x < 10
Therefore, the correct answer is:
D. x < 10
Gina can purchase 10 pizzas and stay under her budget.
