Answer:
a. Determine the total factory overhead amount applied. 
$1,406,600 
b. Calculate the over or under the applied amount for the year.
$8,600 over applied 
Step-by-step explanation:
Estimated factory overhead = $938,600 
Estimated machine hours = 36,100 hours 
Actual Machine hours = 54,100 hours 
Actual Factory overhead = $1,398,000 
Predetermined overhead rate = $938,600 / 36,100 
Predetermined overhead rate = $26 per machine hour 
Applied overhead = Predetermined overhead rate x Actual Machine hours 
Applied overhead = $26 x 54,100 
Applied overhead = $1,406,600 
Over or under the applied amount for the year = Applied overhead - Actual overhead 
Over or under the applied amount for the year = $1,406,600 - 1,398,000 
Over applied amount for the year = $8,600
