Final answer:
The number of equivalent units of production for conversion costs for June, using the FIFO method to cost inventories, is 12,970 units.
Step-by-step explanation:
The number of equivalent units of production for conversion costs for June, using the first-in, first-out (FIFO) method to cost inventories, can be calculated as follows:
- Calculate the equivalent units of production for the units completed during June: 11,500 units * 100% = 11,500 units.
- Calculate the equivalent units of production for the units in process at the beginning of June: 2,000 units * 51% = 1,020 units.
- Add the equivalent units of production for the units completed during June and the units in process at the beginning of June: 11,500 units + 1,020 units = 12,520 units.
- Calculate the equivalent units of production for the units in process at the end of June: 1,500 units * 30% = 450 units.
- Add the equivalent units of production for the units in process at the end of June to the previous total: 12,520 units + 450 units = 12,970 units.
Therefore, the number of equivalent units of production for conversion costs for June, using the first-in, first-out (FIFO) method to cost inventories, is 12,970 units. Therefore, option d. 11,950 units is incorrect.
