Answer:
$1,290
Explanation:
The work in process inventory account balance is given by the sum of the direct material cost, direct labor cost and the amount of applied overhead.
If the balance is $3,850, with material cost of $1,790 and direct labor cost of $770, the applied overhead is:
[tex]O = \$3,850 - \$1,790 - \$770\\O=\$1,290[/tex]
The amount of the applied overhead is $1,290.
