There is always 1 question on the exam about determining cost of Scrap Part Recycled? Anyone know where (what chapter, example problem, etc.) in the MERM 13th i can find similar type of problem to do some practice problem?
I'm not sure where you got your information that "there is always 1 question on the exam about determining cost of scrap part recycled." With that said, I would look at the Engineering Economics chapter.
