D.2. A new flood control project is expected to involve expenditures for periodic heavy mainte- nance as tabulated below. Note that the first expenditure occurs at EOY 2, with subsequent expenditures at four-year intervals, increasing by 20 percent for each expenditure. Find the equivalent annual cost with i= 15 percent per year and n→→ 00. EOY Expenditure 2 $250,000 6 10 300,000 360,000 etc. etc.
