Answer:
B. $210,000
Explanation:
The computation of the contribution margin is shown below:
Contribution margin = Sales - variable cost
where,
Sales revenue = Membership revenue + personal training revenue + product sales
= $142,000 + $76,000 + $66,000
= $284,000
And, the variable cost is
= Cost of goods sold + personal training session expense
= $36,000 + $76,000 × 50%
= $36,000 + $38,000
= $74,000
So, the contribution margin is
= $284,000 - $74,000
= $210,000
