Answer:
To Make Incremantal Costs = $ 912,000
To Buy Incremental Costs = $ 1,140,000
Step-by-step explanation:
incremental costs of making and buying component RX5
To Make Incremantal Costs
Direct materials $ 5.00 × 57,000 units 285,000
Direct labor $9.00 × 57,000 units 513,000
Overhead $10.00 × 20% × 57,000 units 114,000
Totals 912,000
To Buy Incremental Costs
Purchase Price $20.00 × 57,000 units 1,140,000
Totals 1,140,000
Note : Fixed Overheads have been excluded as they are incurred whether or not the Haver Company makes or buys the component RX5. Thus not incremental.
