Question

Solve the problem by writing an inequality.

A club decides to sell T-shirts for $15 as a fundraiser. It costs $20 plus $9 per T-shirt to make the T-shirts.
Write and solve an equation to find how many T-shirts the club needs to make and sell in order to profit
at least $150.

15x- (9x + 20) = 150; X = 28.33
15x - 9x + 20 = 150; x = 20
(8x + 20) – 15x2 150; x = 20
15x – 9(x + 20) 2 150; X 2 20​

Answer 1

Answer:

15x-(9x+20)=150; X=28.33

Step-by-step explanation:

d You can use proccess of elimination to conclude that the answer is the one above because when 20 is plugged in to the second down inequality it comes to, 40 and the last two can not be it because 20 is the constant and 9 is the next to the variable.
