Final answer:
The amount of applied overhead in the Work in Process Inventory account is $1,000.
Step-by-step explanation:
The amount of applied overhead can be calculated by subtracting the direct material cost and direct labor cost from the ending balance of Work in Process Inventory account.
Applied Overhead = Ending Balance - Direct Material Cost - Direct Labor Cost
Applied Overhead = $3,200 - $1,400 - $800
Applied Overhead = $1,000
Therefore, the amount of applied overhead is $1,000.
