Answer:
D. $560 per order
Explanation:
For computing the activity rate first determine the total allocation cost which is shown below:
The Total allocation cost is
= Wages & salaries + depreciation + occupancy
= $420,000 × 20% + $160,000 × 60% + $200,000 * 0.50
= $84,000 $96,000 + $100,000
= $280,000
Now the activity rate is
= $280,000 ÷ 500 orders
= $560 per order
hence, the option D is correct
