Answer: Option (b) is correct.
Step-by-step explanation:
Given that,
Direct materials = $24
Direct labor = $10
Variable overhead = $8
Fixed factory (allocated) = $18
Overtime premium = $8 per unit
Purchased = 2,000 units at a special price of $48 per unit
Contribution Margin (2000 - 1000 units) = special price per unit - Direct materials - Direct labor - Variable overhead
= 48 - 24 - 10 - 8
= $6 per unit
Contribution margin for units produced during overtime = special price per unit - Direct materials - Direct labor - Variable overhead - Overtime premium
= 48 - 24 - 10 - 8 - 7
= $(-1) per unit
Total contribution = 1000 × 6 + 1000 × -1
= $6000 - $1000
= $4000 Profit
Therefore, additional profit will be generated by accepting the special order is $4000.
