1 Quick Computing currently sells 17 million computer chips each year at a price of $28 per chip. It is about to introduce a new chip, and it forecasts annual sales of 22 million of these improved chips at a price of $35 each. However, demand for the old chip will decrease, and sales of the old chip are expected to fall to 2 million per year. The old chip costs $13 each to manufacture, and the new ones will cost $16 each. What is the proper cash flow to use to evaluate the present value of the introduction of the new chip? (Enter your answer in millions.)

8 Kinky Copies may buy a highvolume copier. The machine costs $130,000 and will be depreciated straightline over 5 years to a salvage value of $22,000. Kinky anticipates that the machine actually can be sold in 5 years for $30,000. The machine will save $22,000 a year in labor costs but will require an increase in working capital, mainly paper supplies, of $11,000. The firm’s marginal tax rate is 35%, and the discount rate is 6%. (Assume the net working capital will be recovered at the end of Year 5.)

9 Quick Computing installed its previous generation of computer chip manufacturing equipment 3 years ago. Some of that older equipment will become unnecessary when the company goes into production of its new product. The obsolete equipment, which originally cost $43 million, has been depreciated straightline over an assumed tax life of 5 years, but it can be sold now for $18.6 million. The firm’s tax rate is 35%.

13 Better Mousetraps has developed a new trap. It can go into production for an initial investment in equipment of $5.4 million. The equipment will be depreciated straight line over 6 years to a value of zero, but in fact it can be sold after 6 years for $527,000. The firm believes that working capital at each date must be maintained at a level of 10% of next year’s forecast sales. The firm estimates production costs equal to $1.10 per trap and believes that the traps can be sold for $5 each. Sales forecasts are given in the following table. The project will come to an end in 6 years., when the trap becomes technologically obsolete. The firm’s tax bracket is 35%, and the required rate of return on the project is 9%.
