Answer:
d.$60,400
Explanation:
The computation of the gross margin is shown below:
= Sales - Direct materials cost - Direct labor cost - Overhead cost
where,
Sales = 3,000 units × $29 = $87,000
And all the other items would remain the same
Now put these values to the above formula
So, the value would equal to
= $87,000 - $7,000 - $10,000 - $9,600
= $60,400
