To represent the total cost for each T-Shirt designer based on the number of shirts ordered (x), we can write the following equations:
-
For T-Shirt Designer A: \( y = 20 + 12.5x \)
-
For T-Shirt Designer B: \( y = 30 + 10x \)
So, the equations are:
- Cost for Designer A: \( y = 20 + 12.5x \)
- Cost for Designer B: \( y = 30 + 10x \)
