Answer:
Part a
Differential analysis to determine whether the company should make or buy the bottles.
Make Buy
Variable manufacturing costs ($75 - $28) $47
Purchase price $40
Freight charges $4
Total Cost $47 $44
Part b
The Company should Buy instead of making the bottles. This is because it costs $3 more to make the bottles than buying them.
Step-by-step explanation:
The make or buy decision should be done by considering relevant costs. The fixed costs are irrelevant in this decision hence, we have to ignore them.
The alternative course which gives the lowest cost is the one to go for. This will minimize the costs for the entire business and in turn maximizes the profits of the company.
