Hello Tayba,
Materials EUP is 10,000 as the Materials were added at the beginning, Therefore the Cost per EUP is 15,000 / 10,000 = 1.5$
To get Materials EWIP you shall multiply 1.5 * 2000 (EWIP) = 3,000 $
As for the. Conversion Cost , EUP is (8,000+2000* 70%) = 9,400 EUP
The Cost per EUP for the CC is 25,000 / 9400 = 2.66 $
To get the EWIP , you shall multiply 2.66 * 1400 (EWIP) = 3,720 $
Adding DM + CC to get the EWIP for the Whole process 3,000 + 3,720 =6,720 $
The same Idea for the transferred Cost
For the DM , 1.5 * 8,000(Transferred out Units) = 12,000 $
For the CC , 2.66 * 8,000(Completed units)
= 21,280 $
Total will be 12,000 + 21,280 = 33,280 $
