Explanation:
The overhead will be calcualte as 80% of the labor cost as tstated in the assignment
Then, the total cost will be the sum of the three cost component added during the period andthe beginnign WIP is there is any,
as job 877 is complete it will be removed from WIP leaving only the other three jobs.
the markup is 50% of the cost so we simply multiply cost by 1.5
