To model the fundraising situation for the Lakewood baseball team selling T-shirts, we need to establish two equations: one for the costs and another for the revenue from selling the shirts.
-
Cost Equation: The total cost (y) to produce x shirts includes a fixed setup cost of $100 and a variable cost of $10 per shirt. The equation for the total cost is: \[ y = 10x + 100 \]
-
Revenue Equation: The total revenue (y) from selling x shirts at a price of $15 each is given by: \[ y = 15x \]
So, the two equations that model this situation are:
- \( y = 10x + 100 \) (cost equation)
- \( y = 15x \) (revenue equation)
