Exercise 1-5 differential, sunk, and opportunity costs [lo1-5] northeast hospital’s radiology department is considering replacing an old inefficient x-ray machine with a state-of-the-art digital x-ray machine. the new machine would provide higher quality x-rays in less time and at a lower cost per x-ray. it would also require less power and would use a color laser printer to produce easily readable x-ray images. instead of investing the funds in the new x-ray machine, the laboratory department is lobbying the hospital’s management to buy a new dna analyzer. required: classify each item as a differential cost, a sunk cost, or an opportunity cost in the decision to replace the old x-ray machine with a new machine. if none of the categories apply for a particular item, select "none".
