Answer: B. $132,000
Step-by-step explanation:
When calculating the Segment margin, it is important to note that only costs that are directly traceable to the segment are to be deducted from the revenue.
The segment margin therefore is;
= Sales revenue - Variable costs - Direct fixed costs
= (50,000 * 10) - (50,000 * 6) - 68,000
= 500,000 - 300,000 - 68,000
= $132,000
