Answer:
The Absorption Overhead rate must be used which can be computed using the following formula:
Absorption Overhead Rate (OAR) = Total overhead / Absorption Basis
Here as we know that the absorption basis is labor hours because the overhead costs are driven by the direct labor hours and also that the total overhead is $20,000.
Putting values in the formula:
Absorption Overhead Rate (OAR) = $20,000 / (200 + 800)Hrs = $20 per Hr
Total Overheads share for Product A = $20 per hour * 800 Labor hrs worked on product A = $16,000
For unit Product A = $16000 / 5000 units of A = $3.2 per unit of product A
Similarly for Product B:
Total Overheads share for Product B = $20 per hour * 200 Labor hrs worked on product B = $4000
For unit Product B = $4000 / 2500 units of A = $1.6 per unit of prduct B
