Answer:
It is cheaper to produce
Explanation:
Cost of producing
Direct materials - 90000
Direct labor - 130000
Variable factory overhead - 60000
Fixed factory overhead - 60000
Total cost - 340000
Cost of buying `10000*36 = 360000
Incremental cost of buying = 360000-340000 = $20,000
It is cheaper to produce at 340000/10000 = $34 /unit
In making a decision whether to buy or manufacture , variable cost and the avoidable costs are considered relevant for this purpose
