You are the manager of a large crude-oil refinery. As part of the refining process, a certain heat exchanger (operated at high temperatures and with abrasive material flowing through it) must be replaced every year. The replacement and downtime cost in the first year is $160,000. This cost is expected to increase due to inflation at a rate of 9% per year for six years (i.e. until the EOY 7), at which time this particular heat exchanger will no longer be needed. If the company's cost of capital is 20% per year, how much could you afford to spend for a higher quality heat exchanger so that these annual replacement and downtime costs could be eliminated?
