--------------------------------------------- 
A. Write an equation that gives the production cost in dollars to make one design of t-shirt in terms of the number of t-shirts made. Be sure to describe what your variables represent. Use a complete sentence in your answer. 
C(x) = 22.50 + 7.50x
x is the number of t-shirts made.

B. Write an equation that gives the income (the amount of money that you earn) in dollars in terms of the number of t-shirts sold. Be sure to describe what your variables represent. Use a complete sentence in your answer.
I(x) = 8.25x - [22.50 + 7.50x]  
I(x) = 0.75x - 22.50
x is the number of t-shirts sold.
