i am doing a question from june 2012 question 1 robber company.
i cant get my answer for part (a) for the direct materials keypads
i took $160,000/2 x 1·05 and got 84000 for the direct materials now when i checked the answer they took ($160,000/2) + $160,000/2 x 1·05 and they got $164,000
so i don’t understand why do we have to take $160,000/2 again after doing $160,000/2 x 1·05
