lawyer [7]

Answer:

$29,900

Step-by-step explanation:

= Opening balance of work in process + direct material cost + direct labor cost + factory overhead cost - goods finished

= $7,000 + $78,400 + $195,000 + $136,500 - $387,000

= $29,900

The  direct material cost + direct labor cost + factory overhead cost is known as manufacturing cost

This means that 0.00 is the hundredth place (the bolded 0). Since you round a 9 up one, this makes the 1 in the tenths place go to a 2 and the hundredth go to a 0
