Answer:
Total differential cost= -$73300
Step-by-step explanation:
Equipment rental is equal in both alternatives, so it is not relevant for making a decision.
Costs Alternative A:
Material costs $ 38,000
Processing costs 43,000
Building costs 13,700
Total= $94700
Costs Alternative B:
Material costs $ 66,000
Processing costs $66,00
Building costs $36,000
Total= $168,000
Total differential cost= 168000-94700=$73300
Alternative B costs $73300 more than Alternative A. Based only on this information, alternative A is better than alternative B.
