A process's beginning work in process inventory consists of 10,000 units that are \(20 \%\) complete with respect to conversion costs. A total of 40,000 units are completed this period. There are 15,000 units in ending work in process, one-third complete for conversion. The equivalent units of production (EUP) with respect to conversion at period-end, assuming the weighted average method, are

a. 45,000 EUP.

b. 40,000 EUP.

c. 5,000 EUP.

d. 37,000 EUP.

e. 43,000 EUP.
