Jermaine wants to sell printed t-shirts to raise money for a school dance. He spends $112 to buy a silk-screen machine and ink.
---------------------------
He buys each shirt for $1.75. He sells each shirt for $6.50.
---------------------------
a) Write an equation when y is Jermaine's cost of printing x shirts.
y = 112 + 1.75x

b) Write a second equation where y is the money that Jermaine makes after selling x shirts.
y = 6.5x-1.75x-112
---
y = 4.75x-112
-----------------------

c) Graph the equations. Solve for the point of intersection.
Solve
a) y=112 + 1.75x
b) y=4.75x-112
