Graph a system of equation.

Question

A softball team bought a box of sweatshirts for $240. Each sweatshirt cost $12 to print and will sell for $18. Graph a system of equations to find the number of sweatshirts the softball team needs to sell in order to break even.

Answer 1

They spend $12 per shirt

They make $18 per shirt

 

Let s = # sweatshirts sold

Revenue = (18-12)s = 6s

 

6s = 240

6s = 240

s = 40 shirts to break even
