Answer and Explanation:
The computation is shown below:
The relevant cost is
= Direct material + direct labor + avoidable overhead cost
= $7.80 + $23.80 + ($39 × (1 - 0.40))
= $7.80 + $23.80 + $23.40
= $55 per unit
And, the cost of buying the product is $59 per unit
So here the epsilon should choose to make the product as it less than the buying cost
The same is to be considered
