The school art club at a large high school is in charge of designing school T-shirts and getting them printed this year. A local business charges $35 to set up their T-shirt printing
machine with the design and $4.25 in materials per T-shirt to print.
1. Create an equation to represent the average cost C(x), in dollars, per T-shirt if x
, x
T-shirts are printed by this business.
2. What is the average cost per shirt to print 25 shirts? 100 shirts?
3. What is the cheapest the average cost per T-shirt will get? Explain or show your
reasoning.
4. How many shirts should be printed to have an average cost of $5 or less per shirt?
Explain how you know.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
