Solve the problem by writing an inequality. A club decides to sell T-shirts for $12 as a fund-raiser. It costs $20 plus $8 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 $100. Show your work.

Solution

Selling price = 12

Cost Price (per shirt) = 8

Fixed Cost = 20

Profit = Revenue - Cost

100 = 12 X - (8X +20 )

100 = 4 X - 20

4 X = 120

X = 30

Hence the club needs to sell more than 30 Tshirts to make a profit of atleast 100.

X >= 30
