Answer:
B. $81
Step-by-step explanation:
The incremental cost is the cost of producing an additional unit of output. Incremental costs always comprise of variable costs i.e. costs that fluctuate with changes in the level of output. For example, raw materials, packaging, direct labor and utilities. Understanding of incremental costs is important to boost efficiency and profitability. In the current situation, it is calculated as:
Direct materials: $24
Direct labor: $15
Variable overhead: $30
Variable selling costs: $12
Incremental cost per unit associated with special order: $24 + $15 + $30 + $12 = $81
