Answer:
a. $137,020
Explanation:
The computation of the total variable cost for 5,200 activity level is shown below:
But before that first we have to find out the variable cost per unit which is
= Total variable cost ÷ given activity level
= $131,750 ÷ 5,000 units
= $26.35
Now the variable cost is
= Variable cost per unit × expected activity level
= $26.35 × 5,200 units
= $137,020
We simply applied the above formulas
