1. You are a T-shirt manufacturer that sells to retailers for $17/unit

a. Your cost to make and market the T-shirts= $12/unit
b. What is the ROI?
c. Answer:

The ROI (Return on Investment) can be calculated by subtracting the cost of making and marketing the T-shirts ($12/unit) from the selling price to retailers ($17/unit). Therefore, the ROI is $17/unit - $12/unit = $5/unit.
