A club decides to sell tshirts for $12 each for a fundraiser. It costs $20 plus $8 each Tshirt to make the tshirts. Write and solve an equation to find out how many tshirts the club needs to make and sell to make a profit of at least $100.
.
Profit = revenue - cost
.
Let x = number of tshirts sold
revenue is 12x
cost is 8x+20
.
100 <= 12x - (8x+20)
100 <= 12x-8x-20
100 <= 4x-20
120 <= 4x
30 <= x
.
this says that you have to sell at least 30 tshirts
