2. The unit cost computed above is $21.72 (= $9.17 + $4.55 + $8.00) versus $25.71 on the original
report for the units completed and transferred to finished goods. The unit cost on the original report
is high because none of the cost incurred during the month was assigned to the units in the ending
work in process inventory.

Cost of goods sold = 200,000 units × ($187.50 per unit + $102.50 per
unit) = $58,000,000
2. The estimate of the percentage completion of ending work in process
inventories affects the unit costs of finished goods and therefore the
Ethics Challenge (continued)
The percentage of completion, X, affects the cost of goods sold by its
effect on the unit cost, which can be determined as follows:
$20,807,500
Because the cost of goods sold must be reduced down to $57,800,000,
the unit cost must be $289.00 ($57,800,000 ÷ 200,000 units). Thus, the
required percentage completion, X, to obtain the $200,000 reduction in
cost of goods sold can be found by solving the following equation:
$20,807,500
$187.50 + = $289.00
200,000 + 10,000X
$20,807,500 = $289.00 - $187.50
200,000 + 10,000X
$20,807,500 = $101.50
200,000 + 10,000X
200,000 + 10,000X 1
=
$20,807,500 $101.50
$20,807,500
200,000 + 10,000X = $101.50

4. Mary is in a very difficult position. Collaborating with Gary Stevens in
subverting the integrity of the accounting system is unethical by almost
any standard. To put the situation in its starkest light, Stevens is
suggesting that the production managers lie in order to get their bonus.
Having said that, the peer pressure to go along in this situation may be
Ethics Challenge (continued)
From a broader perspective, if the net profit figures reported by the
managers in a division cannot be trusted, then the company would be
foolish to base bonuses on the net profit figures. A bonus system based
on divisional net profits presupposes the integrity of the accounting
system.
The company should perhaps reconsider how it determines the bonus. It
