Question 538085: Use a system of linear equations to solve this problem.
Suppose you invest $1500 in equipment to put pictures on T-shirts. You buy each T-shirt for $3. After you have placed the pictures on a shirt,you sell it for $20. How many T-shirts must you sell to break even?

You can put this solution on YOUR website!
let number of T shirts for break even be x
1500+3x = C(p)
20x=S(p)
Break even
C(p)=S(p)
1500+3x=20x
17x=1500
x=1700/15
83 shirts
