At the end of October, Laura lamented the company's situation: in the middle of production of Flint-T's most popular long-sleeve T- shirt, the company ran out of its usual collars, purchased from one main supplier. That supplier was also sold out. Flint-T could get a slightly different premade collar, from a new supplier, at the same cost. So Laura went ahead with the order, hoping it wouldn't delay production or affect the quality of the shirts. As it turned out, the new collars failed Flint-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. Direct material Direct labor Manufacturing overhead Total costs Volume in batch $92,000 33,000 16,000 $141,000 20,000 How much cost does Flint-T have tied up in each of these T-shirts? If it normally sells these shirts for $13 to the retailer, how much gross margin per unit does it generate on these sales? (Round answers to 2 decimal places, e.g. 15.25.)
