Answer:
Predetermined overhead rate = Budgeted manufacturing rate/Allocation base
a. <u>Machine hours</u>
= 364,000 / 8,000
= $45.5
Predetermined overhead rate = $45.5
<u />
<u>Direct-labor hours</u>
= 364,000 / 20,000
= $18.2
Predetermined overhead rate = $18.2
<u>Direct-labor dollars</u>
Budgeted labor hours = 20,000 * $14 = $280,000
Predetermined overhead rate = 364,000 / $280,000 = $1.3
b. <u>Machine hours</u>
Manufacturing overhead applied = Actual machine hours * Predetermined overhead rate = $45.5 * 11,000 = $500,500
Over/Under applied overhead = 336,000 - 500,500
Over-applied overhead = $164,500
<u>Direct-labor hours</u>
Manufacturing overhead applied = Actual direct-labor hours * Predetermined overhead rate = $18.2 * 18,000 = $327,600
Over/Under applied overhead = 336,000 - 327,600
Under-applied overhead = $8400
<u>Direct-labor dollars</u>
Manufacturing overhead applied = Actual direct-labor hours * Actual direct-labor rate * Predetermined overhead rate
Manufacturing overhead applied = 18,000 * $15 * $1.3 = 351,000
Over/Under applied overhead = 336,000 - 351,000
Over-applied overhead = $15,000
