Answer :
Answer:
See below.
Explanation:
Lets first calculate variable cost per unit using the highest and lowest activities,
Highest Activity 950 hours $9625 cost in month of May
Lowest activity 720 hours $8360 cost in month of February
Variable cost / unit
= (High activity cost - low activity cost) / (High activity hours - low activity hours)
Variable cost = (9625 - 8360) / (950-720)
Variable cost = $5.5/hour
We can compute the fixed element by multiplying variable cost by hours and subtracting from total cost corresponding to that activity level.
Fixed cost = 8360 - (5.5*720) = $4,400
Hope that helps.
