Answer:
a. Compute the maintenance cost formula
Maintainance cost = $220,000 + $ 2.00 × Number of direct labour hours.
b. cost at an operating level of 52,000 direct labor hours
$324,000
Step-by-step explanation:
a. Compute the maintenance cost formula
Maintainance Cost is a semi-variable cost. This means it has a fixed cost element and a variable cost element.
Cost separation of Maintainance cost is done by using the high - low method as follows :
Variable cost element = difference in Overhead (High - Low)/ difference in Acitivity (High - Low)
= $336,000 - $304,000 / 58,000 - 42,000
= $ 2.00 per direct labour hour
Fixed cost element = Total Overhead - Variable Cost at given activity level
activity level of 58,000 hrs produce the following results
Fixed cost element = $336,000 - $ 2.00 × 58,000
= $220,000
Maintainance cost = $220,000 + $ 2.00 × Number of direct labour hours.
b. cost at an operating level of 52,000 direct labor hours
Maintainance cost = $220,000 + $ 2.00 × Number of direct labour hours.
= $220,000 + $ 2.00 × 52,000
= $324,000
