Gina is having a party and wants to spend less that $380. She has already spent $300. The only item left on her list is pizzas, which cost $10 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.

x < 8 (max number of pizzas is 7)

Step-by-step explanation:

set up an inequality where x = number of pizzas

total < 380 (this is given)

total = 300 + 10x (she already spent 300, and each pizza costs 10 each)

300 + 10x < 380

now solve for x

300 + 10x < 380

10x < 80

x < 8

if she wants to spend less than $380, she needs to buy less than 8 pizzas, so she can buy 7 pizzas at most
