Foulds Company makes 17,000 units per year of a part it uses in the products it manufactures. The unit product cost of this part is computed as follows:

Direct materials 13.90 Direct labor 21.50 Variable manufacturing overhead 3.70 Fixed manufacturing overhead 11.60 Unit product cost 50.70 An outside supplier has offered to sell the company all of these parts it needs for S43.00 a unit. If the company accepts this offer, the facilities now being used to make the part could be used to make more units of a product that is in high demand. The additional contribution margin on this other product would be S18, 700 per year. If the part were purchased from the outside supplier, all of the direct labor cost of the part would be avoided. However, S5.70 of the fixed manufacturing overhead cost being applied to the part would continue even if the part were purchased from the outside supplier. This fixed manufacturing overhead cost would be applied to the company's remaining products. Required: a. How much of the unit product cost of S50.70 is relevant in the decision of whether to make or buy the part? (Round your answer to 2 decimal places.) Relevant cost per unit b. What is the net total dollar advantage (disadvantage) of purchasing the part rather than making it? (Input the amount as a positive value.) Net c. What is the maximum amount the company should be willing to pay an outside supplier per unit for the part if the supplier commits to supplying all 17,000 units required each year? (Round your answer to 2 decimal places.)
