Answer:
a. $ 900 underapplied
Step-by-step explanation:
Based on the data provided we conclude that the factory overhead is applied on the basis of direct labour hours.
Determination of Overhead rate
Estimated overhead $ 115,000
Direct labour hours 23,000 hours
Overhead rate per direct labor hour is $ 115,000/ 23,000 = $ 5 per direct labor hour
Amount of applied overhead = Direct Labor hours * Overhead rate per hour
Applied Overhead = $ 5 * 35,000 $ 175,000
Actual Overhead $ 175,900
Underapplied Overhead $( 900)
