Answer and Explanation:
The computation is shown below:-
a. Total variable cost
= Number of units × (Variable cost ÷ Number of units)
= 3,200 × ($155,620 ÷ 3,100)
= $160,640
b. Total fixed cost
= $68,000
c. Total cost
= Total variable cost + Total fixed cost
= $160,640 + $68,000
= $228,640
d. Average variable cost per unit
= Variable cost ÷ Number of units
= $155,620 ÷ 3,100
= $50.20
e. Average fixed per unit
= Fixed cost ÷ Number of units
= $68,000 ÷ 3,100
= $21.93
f. Average total cost per unit
= Average variable cost per unit + Average fixed per unit
= $50.20 + $21.93
= $72.13
