Answer :
Answer:
$4.44 per machine hour
Explanation:
The computation of the activity rate for the fabrication cost pool is shown below:
= (Wages and salaries × given percentage + depreciation × given percentage + occupancy × given percentage) ÷ (fabrication hours)
= ($280,000 × 60% + $200,000 × 20% + $140,000 × 10%) ÷ (50,000 machine hours)
= ($168,000 + $40,000 + $14,000) ÷ (50,000 machine hours)
= $4.44 per machine hour
