Quick Computing currently sells 11 million computer chips each year at a price of $31 per chip. It is about to introduce a new chip, and it forecasts annual sales of 21 million of these improved chips at a price of $39 each. However, demand for the old chip will decrease, and sales of the old chip are expected to fall to 1 million per year. The old chips cost $16 each to manufacture, and the new ones will cost $10 each. What is the proper cash flow to use to evaluate the present value of the introduction of the new chip?
