A. only direct labor and direct materials costs.
B. some costs incurred during the prior period as well as costs incurred during the current period.
C. only costs incurred during the current period.
D. some period costs as well as some product costs.

2. During the month of August, direct labor cost totaled \$13,000 and direct labor cost was 20% of prime cost. If total manufacturing costs during August were \$88,000, the manufacturing overhead was:
A. \$52,000
B. \$75,000
C. \$65,000
D. \$23,000

0.20 x Prime cost = Direct labor
0.20 x Prime cost = \$13,000
Prime cost = \$65,000
Prime cost = Direct materials + Direct labor
\$65,000 = Direct materials + \$13,000
Direct materials
\$5.00
B. \$10.00
C. \$4.00
D. \$8.00
Equivalent units for materials = 5,000 x 80% = 4,000
Equivalent units for conversion = 5,000 x 50% = 2,500
Ending inventory dollar value = \$60,000
Ending inventory dollar value = (Equivalent units for materials x Cost per equivalent unit for materials) + (Equivalent units for conversion x Cost per equivalent unit for conversion)
\$60,000 = (4,000 x Cost per equivalent unit for materials) + (2,500 x \$8.00)
\$60,000 = 4,000x X + \$20,000
X = \$10.00
