Direct labor (0.75 hours at $8 per hour)..................................$6.00

Variable overhead (0.75 hours at $3 per hour).........................$2.25

Actual experience for current year:

Units produced.........................................................................22,400 units

Purchases of raw materials (21,000 grams at $17 per gram)...$357,000

Raw materials used..................................................................33,400 grams

Direct labor (16,750 hours at $8 per hour)..............................$134,000

Variable overhead cost incurred...............................................$48,575
