Your job is to calculate costs for the various orders. For each order, U. S. Shirts charges \$8 per shirt plus a one time set up charge of \$15. 1. Write an equation using the information above to show the relationship between the number of shirts the total cost. Let n = number of shirts and c = cost. 2. Use your equation from #1 to show how much U.S. Shirts would charge for an order of 3 shirts? Show work/explain. 3. How many shirts could a customer purchase with \$63 at U.S. Shirts? Show work/ explain. 1
2. 2. Part B A competitor's advertisement (T-Shirt World) states that they will make custom tee shirts for \$5 a shirt with a one time set up fee of \$45. When your boss sees this ad, he tells you to figure out how this might affect his business. 1. Write an equation using the information above to show the relationship between the number of shirts the total cost for T-Shirt World. Let n = number of shirts and c = cost. 2. Use your equation to show how much T-Shirt World charges for an order of 3 shirts? Show work/explain. 3. How many shirts could a customer purchase from your competitor with \$90? Explain/show work. 2

How many shirts can a customer order and pay the same amount at each company? Explain how you found your answer. 3
4. 4. Part D—Solving Equations Solve the following equations by finding the value of x. Show your work symbolically!!! Write you answer on the line. Show your check!!! 1. Find x if, 10 = 5 x – 40 check: x=_________ 2. Find x if, 27= -5 x + 2 check: x=__________ 4
