You are given a job cost sheet as follows:
For 2,000 units
DM = Direct Materials, DL = Direct Labour, MOH = Manufacturing Overhead

Jan. 1 - DM = $5000, DL = $6000, MOH = $4500
Jan. 8 - DM = $6000, DL = 0, MOH = 0
Jan. 12 - DM = 0, DL = $8000, MOH = $6400
Jan. 25 - DM = $2000, DL = 0, MOH = 0
Jan. 27 - DM = 0, DL = $4000, MOH = $3200
Totals: DM = 13,000, DL = 18,000, MOH = 14,100
Total Cost = $45,100
Unit Cost = $22.55

Questions:
1. What was the balance in the Work In Process inventory on January 1 if this was the only job unfinished?

2. If MOH is applied on the basis of direct labour cost, what overhead rate was used in each year?

3. Prepare summary entires at Jan 31 to record the current years transacations pertaining to this job

Im not entirely sure how to complete this, I think the WIP balance might be 15,500, but im not sure if thats right, and im unsure how to answer the other questions. Any help would be great.
