Answer:
The variable cost per unit at the 200,000 units amounts to $300,000.
Step-by-step explanation:
Computing the variable cost is as:
Total fixed and variable cost = Fixed cost + Variable cost
$420,000 = $225,000 + Variable cost
Variable cost = $420,000 - $225,000
Variable cost = $195,000
Now,
we will compute the variable cost per unit which is as follows:
Variable cost per unit = Variable Cost / Units
= $195,000 / 130,000
= $1.5
Therefore, the variable cost per unit is $1.5
So, for 200,000 units it will be:
= Variable cost per unit × Units
= $1.5 × 200,000
= $300,000
