Answer:
Total relevant cost = $143,288
Step-by-step explanation:
In a make-or buy decision , to determine the optimal course of action we compare the purchase cost of the component from the external market to the relevant variable cost of internal production. Where the relevant cost of in-house production is less than the external price, the company should produce internally and vice versa
Differential cost per unit = 16 - 12 = $4
Total relevant cost = $4× 35,822 = $143,288
Total relevant cost = $143,288
Note the fixed cost of $10 per unit is exclude because it is not relevant ; it would be incurred either way
