In a recent advertisement, Patagonia touted the advantages of a wet suit that it makes and sells. The company stated the following: "It takes 6 hours and 45 minutes to make one Patagonia wet suit. Thats a long time, but building something to perform perfectly for years of hard use cant be rushed. We make our wet suits by hand with limestone-based neoprene. We line them with either recycled polyester Regulator grid fleece, or a Regulator fleece/merino wool blend in our warmer suits. Were meticulous we insist that every detail be totally dialed so that your wet suit seems to disappear when you paddle out. But theres more to quality than performance. A comfortable, well-built suit means you dont have to buy a new one anytime soon, and we wont have to make another one which means using fewer resources that the environment cant readily replace." Describe how Patagonia should compute the cost of making a wet suit.
