$110,000
2. Of the $110,000 in materials requisitioned for production, $90,000 was
als.

Problem 3-22 (30 minutes)
1. The predetermined overhead rate was:
Y = $795,000 + $1.40 per hour × 75,000 hours
Estimated fixed manufacturing overhead ..................
$795,000
Estimated variable manufacturing overhead
$1.40 per computer hour × 75,000 hours...............
105,000
Estimated total manufacturing overhead cost ............
$900,000
The predetermined overhead rate is computed as follows:
Estimated total manufacturing overhead ........
$900,000
÷ Estimated total computer hours .................
75,000
hours
= Predetermined overhead rate ....................
$12.00
per hour
