Dubberly Corporation's cost formula for its manufacturing overhead is $32,200 per month plus $66 per machine-hour. For the month of March, the company planned for activity of 7,840 machine-hours, but the actual level of activity was 7,770 machine-hours. The actual manufacturing overhead for the month was $573,970.

A. 24330 U

B. 24330 F

C. 28950 U

D. 28950 F

C. $28,950 Unfavorable

Explanation:

The calculation of spending variance for manufacturing overhead is given below:-

Budgeted manufacturing overhead for actual activity = Manufacturing overhead + (Actual level of activity * Machine per hour)

= $32,200 + (7,770 * $66)

= $545,020

Spending variance for manufacturing overhead = Actual Manufacturing overhead for the month - Budgeted manufacturing overhead for actual activity

= $573,970 - $545,020

= $28,950 Unfavorable
