You have taken a new job at Happy Shirts, a custom T-shirt shop. One of your responsibilities is to calculate the price of the orders. For each order, Happy Shirts charges $7.25 per shirt, plus a one-time charge of $32.50 to set up the design. 1. How much will you charge for an order of: a. 4 shirts?b. 10 shirts?c. 100 shirts? In a complete sentence, describe how you found your answers.

2. How many shirts can a customer purchase with: a. $50? b. $100? c. $500? In a complete sentence, describe how you found your answers. 3. Make a table of values based on the problem situation. Number of Shirts OrderedTotal Cost Number of ShirtsDollars

Reflect on the work you have just completed for this problem situation to answer the following questions. Answer in complete sentences. 4. What are the variable quantities in the problem situation? Include the units used to measure these quantities. 5. What are the two constant quantities in the problem situation? Include the units used to measure these fixed quantities. 6. Of the two variable quantities, which quantity depends on the other quantity? Number of Shirts OrderedTotal Cost Number of ShirtsDollars Happy Shirts charges $7.25 per shirt, plus a one-time charge of $32.50 to set up the design. Total cost depends on the number of shirts ordered.
