Answer: The customer cost for combined shipping and returns of Product 1 is $6.25 per unit.(option c)
We arrive at the answer as follows:
A. Calculating cost of returns
[tex]Cost of returns = Cost per returns * Number of returns[/tex]
[tex]Cost of returns = 45 * 150[/tex]
[tex]Cost of returns = 6750[/tex]
B. Calculating Cost of shipments
[tex]Cost of shipments = Rate per shipment * Number of shipments[/tex]
[tex]Cost of shipments = 10 * 1200[/tex]
[tex]Cost of shipments = 12000[/tex]
C.Calculate total cost of shipments and cost of returns
[tex]Total Cost = Cost of shipments + Cost of returns[/tex]
[tex]Total Cost = 12000 + 6750[/tex]
[tex]Total Cost = 18750[/tex]
D. Calculate cost per unit
[tex]Cost per unit = \frac{Total Cost}{Number of units shipped}[/tex]
[tex]Cost per unit = \frac{18750}{3000}[/tex]
[tex]Cost per unit = 6.25[/tex]
