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 $180 comma 000180,000. this cost is expected to increase due to inflation at a rate of 66% per year for sixsix years (i. e. until the eoy 77), at which time this particular heat exchanger will no longer be needed. if the company's cost of capital is 2020% 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?
