Question

Refries Refrigerator Company manufactures ice-makers for installation in refrigerators. The costs per unit for 20,000 units of ice-makers, are as follows:

Direct materials. ....... $7
Direct labor.......... $12
Variable overhead ......$5
Fixed overhead............$10
Total costs ...................$34
Cool Compartments Inc. has offered to sell 20,000 ice-makers to Refrigerator Company for $28 per unit. If Refrigerator accepts Cool Compartments' offer, the facilities used to manufacture ice-makers could be used to produce water filtration units. Revenues from the sale of water filtration units are estimated at $80,000, with variable costs amounting to 60% of sales. In addition, $6 per unit of the fixed overhead associated with the manufacture of ice-makers could be eliminated. For Refrigerator Company to determine the most appropriate action to take in this situation, the total relevant costs of make vs. buy, respectively, are:____.
a. $600,000 vs. $560,000.
b. $648,000 vs. $528,000.
c. $600,000 vs. $528,000.
d. $680,000 vs. $440,000.

Answer 1

c. $600,000 vs. $528,000.

Step-by-step explanation:

The computation of the relevant cost of make & buy is given below:

Total relevant cost of making the product is

= (cost per unit - unavoidable fixed cost per unit ) × 20,000 units

= ($34 - $4 ) × 20,000 units

= $600,000.

And, Total relevant cost of buying is

= (cost of buy per unit × 20,000 units ) - Contribution sale of water filtration = ( $28 × 20,000 units ) - ($80,000 - 60% of $80,000)

= $528,000

hence, the option c is correct
