Answer
1. D 400,000
2. D 6
Explanation:
a.Variable manufacturing overhead for the year = Variable manufacturing overhead rate per machine-hour × Total machine-hours required for the year
$4× 100,000 machine-hours
= $400, 000
b.Predetermined overhead rate = (Variable manufacturing overhead + Fixed manufacturing overhead) / Total machine-hours required
($4 × 100,000 machine- hours) + ($50,000 per quarter × 4 quarters) / 100,000
=($400,000 + $200,000) / 100,000 machine-hours.
= $600,000/100,000 = $6 per machine hours
