Haver Company currently produces component RX5 for its sole product. The current cost per unit to manufacture the required 70,000 units of RX5 follows. Direct materials $ 4.00
Direct labor 8.00
Overhead 9.00
Total costs per unit 21.00
Direct materials and direct labor are 100% variable. Overhead is 80% fixed. An outside supplier has offered to supply the 70,000 units of RX5 for $20.00 per unit.
Required:
1. Calculate the incremental costs of making and buying component RX5.
Total incremental costs of: Making the units Buying the units
Total direct materials $ 244,000 $ 0
Total direct labor 488,000 0
Variable overhead costs 122,000 0
Cost to buy the units 1,159,000
Total costs $ 854,000 $ 1,159,000
Should the company continue to manufacture the part,
or should it buy the part from the outside supplier? Make the units

1.Incremental cost of making and buying the RX5 is $434,000

2. Since the cost of buying is more than the cost of producing by $305,000, therefore, the company should continue to produce the component parts.

Explanation:

1.We need to first compute the cost of making the component part.

Cost of making are;

Direct material = 70,000 units × $4

= $280,000

Direct labor = $70,000 units × $8

= $560,000

Variable over head cost = 70,000 units × $9 × 20%

= $126,000

Therefore, total cost of making the components = direct material cost + direct labor cost + variable overhead cost

= $280,000 + $560,000 + $126,000

= $966,000

Also, total cost of buying the components

= Units × RX5 per unit

= 70,000 × $20

= $1,400,000

Therefore,

Incremental cost = Cost of making - Cost of buying

= $966,000 - $1,400,000

=$434,000

2. Total costs of making the units = Total direct material cost + Total direct labor costs + Variable overhead costs

= $244,000 + 488,000 + $122,000

= $854,000

Since total cost to buy is $1,159,000

Total incremental cost = Total cost of making the units - Total cost of buying the units

= $854,000 - $1,159,000

= $305,000

answer; (a) calling people who have not shown interest in the product and asking them to buy it;

the answer to this question would be shared investment
