Answer:
$1657500 applied and $17500 overapplied
Explanation:
The computation of overhead applied and the under- or overapplication of overhead for the period is shown below:-
Predetermined overhead rate = Estimated annual overhead ÷ Estimated machine hours
=($1,700,000 ÷ 400,000)
= $4.25 per machine hours
Overhead applied = Predetermined overhead rate × Actual machine hours
= $4.25 × 390,000
= $1,657,500
The overhead applied is lower than the actual overhead cost;
overhead underapplied = $1,675,000 - $1,657,500
= $17,500
