Despite Liston's attempts to knock out a blinded Clay, Clay was able to survive the fifth round until sweat and tears rinsed the irritation from his eyes. In the sixth, Clay dominated, hitting Liston repeatedly. Liston did not answer the bell for the seventh round, and Clay was declared the winner by TKO . Liston stated that the reason he quit was an injured shoulder. Following the win, a triumphant Clay rushed to the edge of the ring and, pointing to the ringside press, shouted: "Eat your words!" He added, "I am the greatest! I shook up the world. I'm the prettiest thing that ever lived." 
EnterTech has noticed a significant decrease in the profitability of its line of portable CD players. The production manager believes that the source of the trouble is old, inefficient equipment used to manufacture the product. The issue raised, therefore, is whether EnterTech should (1) buy new equipment at a cost of $120,000 or (2) continue using its present equipment. It is unlikely that demand for these portable CD players will extend beyond a five-year time horizon. EnterTech estimates that both the new equipment and the present equipment will have a remaining useful life of five years and no salvage value. The new equipment is expected to produce annual cash savings in manufacturing costs of $34,000, before taking into consideration depreciation and taxes. However, management does not believe that the use of new equipment will have any effect on sales volume. Thus, its decision rests on the magnitude of the potential cost savings. The old equipment has a book value of $100,000. However, it can be sold for only $20,000 if it is replaced. EnterTech has an average tax rate of 40 percent and uses straight-line depreciation for tax purposes. The company requires a minimum return of 12 percent on all investments in plant assets.
