The freshman class is selling t-shirts to raise money for a field trip cost of each costume design t-shirt is eight dollars there is a $45 fee to create the design the class plans to sell the search for $12 what is the cost and revenue function

Cost = 8x - 45 and Revenue = 12x

In this situation, the cost of each shirt is 8 plus there is a 45 fee. So we can write the equation C = 8x - 45, where x is the number of shirts sold.

To find the revenue, you just multiply the number of shirts by 12. Therefore, the equation is just R = 12.
