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

We know the time is 8 seconds so since it’s 2.5t and t is 8 do 8x2.5 and you will get 20 so now we now 2.5t is 20 but they want the height and so you plug it into the equation h=40-20 and so h is 20
