Question 399796
 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
---------
{{{graph(400,300,-10,100,-20,400,1.75x+112,4.75x-112)}}}
Point of intersection: (74 2/3,242 2/3)
