Question 410881: Suppose you invest $1530 in equipment to put your school logo on T-shirts. You buy each T-shirt for $3. After you have placed the logo on a shirt, you sell the shirt for $20. How many T-shirts must you sell to break even? (could you also explain how you got the answer?)

You can put this solution on YOUR website!
Let t = number of t-shirts you must sell
1530+%2B+3t+=+20t
This equation says
(money spent to make t t-shirts) = (money made on t t-shirts)
17t+=+1530
t+=+90
You must sell 90 t-shirts to break even
