When the Senior class decided to order Tshirts, they were quoted a price of $7.50 per shirt plus a setup fee. The total cost for 300 shirts was $2,450. Write an equation in the form y = mx + b that represents the cost, y, for x shirts.

MathMate,
Here
m=7.50 / shirt
b=setup fee
Since we know that
2450=7.5(300)+b
=>
b=24507.50*300
=24502250
=200
So
y=7.50x+200
