Solutions to Questions
4-1 A process costing system should be used in situations where a homogeneous product is produced on a continuous basis.
4-2 Job-order and processing costing are similar in the following ways:1. Job-order costing and process costing have the same basic purposes—to assign materials, labor, and overhead cost to
products and to provide a mechanism for computing unit product costs.2. oth systems use the same basic manufacturing accounts.
!. "osts #ow through the accounts in basically the same way in both systems.
4-3 "ost accumulation is simpler under process costing because costs only need to be assigned to departments—notindividual $obs. A company usually has a small number of processing departments, whereas a $ob-order costing system oftenmust %eep trac% of the costs of hundreds or even thousands of $obs.
4-4 &n a process costing system, a 'or% in (rocess account is maintained for each processing department.
4-5 )he $ournal entry to record the transfer of wor% in process from the *i+ing epartment to the iring epartment is:
'or% in (rocess, iring............................. ...
'or% in (rocess,*i+ing................................................
4-6 )he costs that might be added in the iring epartment include: /10 costs transferred in from the *i+ing epartment /20materials costs added in the iring epartment /!0 labor costs added in the iring epartment and /0 overhead costs added inthe iring epartment.
4-7 3nder the weighted-average method, e4uivalent units of production consist of units transferred to the ne+t department/or to 5nished goods0 during the period plus the e4uivalent units in the department6s ending wor% in process inventory.

And the cost of goods sold can be computed as follows:
"ost of goods sold H 297,777 @ 3nit cost
ecause the cost of goods sold must be reduced down toC=1,912,977, the unit cost must be C2=.79 /C=1,912,977 E297,777 units0. )hus, the re4uired percentage completion, , toobtain the C=2,977 reduction in cost of goods sold can be foundby solving the following e4uation:

rom a broader perspective, if the net pro5t 5gures reported bythe managers in a division cannot be trusted, then thecompany would be foolish to base bonuses on the net pro5t5gures. A bonus system based on divisional net pro5tspresupposes the integrity of the accounting system.
)he company should perhaps reconsider how it determines thebonus. &t is 4uite common for companies to pay an Sall ornothingT bonus contingent on ma%ing a particular target. )hisinevitably creates powerful incentives to bend the rules whenthe target has not 4uite been attained. &t might be better tohave a bonus without this Sall or nothingT feature. or e+ample,managers could be paid a bonus of + of pro5ts above targetpro5ts rather than a bonus that is a preset percentage of their
base salary. 3nder such a policy, the eOect of adding that lastdollar of pro5ts that $ust pushes the divisional net pro5ts overthe target pro5t will add a few pennies to the manager6scompensation rather than thousands of dollars. )herefore, theincentives to misstate the net operating income are reduced.'hy tempt people unnecessarilyV
