1- An engineer has a fluctuating future budget for the maintenance of a particular machine. During each of the first 5 years, $1000 per year will be budgeted. During the second 5 years, the annual budget will be $1500 per year. In addition, $3000 will be budgeted for an overhaul of the machine at the end of the fourth year, and another $3000 for an overhaul at the end of the eighth year. The engineer asks you to compute the uniform annual expenditure that would be equivalent to these fluctuating amounts, assuming interest at 8% per year.

An engineer has a fluctuating future budget for the maintenance of a particular machine. During each of the first 5 years, $1000 per year will be budgeted. During the second 5 years, the annual budget will be $1500 per year. In addition, $3500 will be budgeted for an overhaul of the machine at the end of the fourth year, and again at the end of the eighth year. What uniform annual expenditure (cost) would be equivalent, if interest is 9% per year?

Lubbock County is planning to construct a bridge across the Rio de Lubbock to facilitate afternoon skiing in the El Dusto Ski Basin. The first cost for the bridge will be $6,500,000. Annual maintenance and repairs will cost $25,000 for each of the first five years, increase to $30,000 for each of the next ten years, and increase again to $35,000 for each of the next five years. In addition, a major overhaul costing $500,000 will be required at the end of the tenth year. Use an interest rate of 5% and determine the equivalent uniform annual cost for a 20-year period.
