Answer: Financial disadvantage of -$30,800
Explanation:
If purchased externally then the equipment used in production will no longer be used therefore its depreciation would be irrelevant to the unit.
The fixed costs would be incurred regardless so will not factor in the decision either.
Therefore the total relevant cost of producing internally is;
= (Direct materials + Direct labor + Variable overhead + Supervisor's salary) * Units produced
= (3.7 + 3.6 + 1.4 + 4) * 7,000
= 12.7 * 7,000
= $88,900
If Part U98 is purchased from outside at $17.10 a unit;
= 7,000 * 17.10
= $119,700
Total Financial advantage (disadvantage)
= Variable cost and supervisor salary - Cost of purchasing outside
= 88,900 - 119,700
= -$30,800
= (30,800)
