Answer:
Ripka Company
The relevant cost for Ripka to consider in making its decision is:
b. $30,000 for reworking the units
Step-by-step explanation:
a) Data and Calculations:
Inventory = 20,000 units
Production cost already incurred = $4 per unit
Total production cost = $80,000 (20,000 * $4)
Total Cost of Reworking the units = $30,000
Sales revenue after rework = $35,000
Alternative sales revenue without reworking = $10,500
b) Relevant cost is the avoidable cost. The cost that can be avoided in this instance is the cost of reworking the units, amounting to $30,000.
