At the end of October, Sarah lamented the company's situation: in the middle of production of Sage-T's most popular long-sleeve Tshirt, the company ran out of its usual collars, purchased from one main supplier. That supplier was also sold out. Sage-T could get a slightly different premade collar, from a new supplier, at the same cost. So Sarah went ahead with the order, hoping it wouldn't delay productioit or affect the quality of the shirts. As it turned out, the new collars failed Sage-T's quality control testing. Stuck with unwearable T-shirts, the company was also in a bind with its retail outlets which wanted more shirts to sell! The costs to produce this most recent batch of shirts is as follows. How much cost does Sage-T have tied up in each of these T-shirts? If it normally sells these shirts for $11 to the retailer, how much gross margin per unit does it generate on these sales? (Round answers to 2 decimal places, eg. 15.25.) Total cost /unit Gross margin /unit Scrambling, Sarah has gone back to her original supplier of collars, which thankfully now has a large quantityit can ship to her. These collars cost $0.60 each, and the company can get enough of them to go back and fix the collars on the recently ruined batch. plus put some into the warehouse for a future batch. In order to fix the botched T-shirts, though, Sage-T will need to ineur an extra $2 per shirt in labor costs to carefully remove the bad collars and re-attach the new ones. These reworked shirts should still be salable to retailers at the regular selling price. How much gross margin per unit will Sage-T generate if it fixes and sells these reworked shirts? (Round answer to 2 decimal places, e.8. 15.25.) Gross margin \$ In the decision of whether or not to rework the bad batch of T-shirts, how much of the T-shirt cost was sunk? (Round answer to 2 decimal places, e.g. 15.25.) Sunk cost /shirt If Sage-T could have sold the botched shirts in as-is condition for $8.90 per shirt to a salvage store, would it have been better off than fixing them? Gross margin /unit Sage-t would have been selling them as-is
