   for 0 through 15 shirts.

2. There are 10 people on the team. Do they save money if they buy an extra shirt? Explain your reasoning.
3. What is the slope of the graph between 0 and 10? What does it mean in the story?
4. What is the slope of the graph between 11 and 15? What does it mean in the story?
