Question

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 sell in order to make a profit of at least $100.

Answer 1

12X - (20 + 8X) = 100
solve for X

Answer 2

Do you by any chance know the equation to how many T-shirts the club needa??

Answer 3

I have written equation in terms of X see..
simplifying it becomes 4X-20= 100...
4X=120
X=30

Answer 4

it says at least $100....so this is supposed to be an inequality.
swarup did it correctly except it should be :
12x - (20 + 8x) >= 100
12x - 20 - 8x >= 100
4x >= 120
x >= 30
The club would have to sell 30 or more shirts to make a profit of $100

all is the same as swarup, except be sure and put an inequality sign instead of just an equal sign.
