Answer:
$50 per unit.
Step-by-step explanation:
Relevant cost are the only cost that will be affected by the management decision to produce the special order. All fixed costs are sunk costs and are therefore irrelevant to the decision. Since to selling cost will be incurred, this implies that only the Variable manufacturing $50 is relevant.
Therefore, the proper relevant cost in deciding whether to accept this special order would be $50 per unit.
And the total relevant cost would be:
Total relevant cost to order no 656 = Number of units * Variable manufacturing = 5,900 * $50 = $295,000.
