Answer and Explanation:
1. The computation of total incremental is shown below:-
Incremental Costs to Make
Relevant Amount Relevant Fixed Total Relevant
Per Unit Costs Costs
Variable Cost
Per Unit $4.05 $166,050
(41,000 × $4.05)
Fixed manufacturing
cost $83,000 $83,000
Total incremental
cost to make $249,050
Incremental Costs to Buy
Purchase Price Relevant Fixed Total Relevant
Per Unit Costs Costs
Purchase Price
Per Unit $143,500
($3.50 × 41,000)
Total Incremental Cost to Buy $143,500
2. The company should buy from the outside supplier as its a lower and the total incremental cost is $143,500
