A company's financial analyst is advising the management that an investment in new technology will save it money at the rate of
S'(t)=4,000(1-0.07e^(-0.07t))
dollars per month t months after the purchase of the new technology.
The analyst advised the management that if it purchases the new technology, it will save, through the next 24 months, just over $100,000. As a manager, would you accept or reject the analyst's claim? Explain.
The savings over the next 24 months are $92,746, so the analyst's claim is too high. It should be rejected.
