3. (20%) A certain wind turbine is rated at 5 MW and has an installed cost of $6,000,000. The capacity factor is 0.38. The turbine is paid for with a down payment of 1/10 of the installed cost and a loan. The loan interest rate, b, is 8% and the period of the loan, N, is 15 years. The economic lifetime of the turbine, L, is to be 20 years, the inflation rate is...
