QLink QLink is considering entering a market where annual consumer demand is given by the equation Q = 102 -P. To enter this market, QLink must invest $2,000 in a machine with no resale value that has a useful life of one year. Labor to run the machine costs $20 per hour. Without the machine, nothing can be produced. With the machine, it takes 1/10 hour to produce one unit. Suppose QLink enters the market, but then demand changes to Q=36-P. Now what are QLink's profits? When, if ever, should QLink exit the market
