Dr Work in process 48,100 
(260 hours ×185 per hour)

Dr Work in process 30,000 
Cr Consultant fees payable 30,000 
27-Jul
Dr Work in process 26,660
(170 hours +260 hours)*62 
Cr Office overhead 26,660

31-Jul
Dr Accounts receivable 172,500 
Cr Fees earned 172,500
31-Jul 
Dr Cost of services 142,760
(25,500+12,500+48,100+30,000+26,660)
Cr Work in process 142,760 
b. Calculation for how much office overhead isover- or underapplied
(28,500+4,000)-26,660
=32,500-26,660
=$5,840
Therefore the office overhead is over applied with $5,840 
C. Calculation to Determine the gross profit on the Obsidian case
Fees earned 172,500
Less Cost of services (136,920)
(142,760-5,840)
Gross profit $35,580 
 
Therefore the gross profit on the Obsidian case, assuming that over- or underapplied office overhead is closed monthly to cost of services will be $35,580
