Answer:
The correct option is a. the variable cost is $330,750 and fixed cost is $414,000.
Explanation:
For computing the correct figures of variable cost and fixed cost for 21,000 units, first we have to calculate the variable cost per unit.
So,
Variable cost per unit = Total variable cost ÷ Number of units
= $362,250 ÷ 23,000
= $15.75 per unit
SO, variable cost for 21,000 units = Number of units × per unit price
= 21,000 × $15.75
= $330,750
Hence, the variable cost for 21,000 units is $330,750
Since the fixed cost remained fixed whether production level is increased or not. So, fixed cost would be $414,000
Therefore, the correct option is a. the variable cost is $330,750 and fixed cost is $414,000.
