Answer: $12.20
Step-by-step explanation:
Total Manufacturing cost at 8,500 units;
= Direct materials + Direct labor + Variable Manufacturing Overhead + Fixed manufacturing overhead
= (6.9 * 8,500) + ( 3.9 * 8,500) + ( 1.4 * 8,500) + 102,850
= $206,550
Total Manufacturing cost at 8,501 units;
= (6.9 * 8,501) + ( 3.9 * 8,501) + ( 1.4 * 8,501) + 102,850
= $206,562.20
Incremental cost = 206,562.2 - 206,550
= $12.20
