Consider Problem 2.13 where, in this case, each process is capable of rework. Given the information in the following table, what is the input required to satisfy a demand of 1,000 units? Suppose that scrap costs are negligible, and rework costs are $2,$3, and $4, respectively. Calculate the rework cost for producing the 1,000 units. What happens to the rework cost if the scrap rates on processes 1 and 3 are reversed? Does this result agree with that of Problem 2.13
