The reason you don't multiply EI by 80% or BI by 60% in this problem is because the problem says direct materials are added when the process is 70% complete. So if process is less than 70% complete, there is 0% DM, and if the process is more than 70% complete, it's 100% DM.
So instead of 170,000 + 20000 (25,000 x.8) - 12000(20,000 X .6) you do 170,000 + 25000 (25,000 x1) - 0 (20,000 X 0)
