Answer:
a. $61,915
Explanation:
We summarize the information first,
Standard level of activity = 5800 hrs
Standard Fixed Costs = $58,870
Standard Fixed cost / hour = $10.15
This is the standard rate used for absorption; applying this to actual activity levels gives us the total fixed manufacturing overheads applied for the period.
Applied overhead = 10.15 * 6,100 (actual activity level) = $61,915
This is the amount that is charged and is over-absorbed by
Over-absorption = 61,915 - 58,320 = $3,595. This will be adjusted in the income statement.
Hope that helps.
