Answer:
a.
VC/unit = $3 per unit
Fixed Cost = $800
b.
Total Cost = $25400
Step-by-step explanation:
a.
The high-low method is used to separate the components of a mixed cost and it calculates the variable cost component in a mixed cost. The formula to calculate the variable cost per unit under the high-low method is as follows,
VC/unit = [Highest Activity cost - Lowest Activity Cost] / [Highest Activity units - Lowest Activity units]
VC/unit = [22400 - 6500] / [7200 - 1900]
VC/unit = $3 per unit
Using figures from March, The total fixed costs will be,
Fixed cost = 6500 - [3 * 1900]
Fixed Cost = $800
b.
Total cost in a month with 8200 units will be,
Total Cost = Total Fixed cost + Total variable costs
Total Cost = 800 + (3 * 8200)
Total Cost = $25400
