pls answer 2.17R

2.17 Assume the cost of a homeland security border fence is $3 million per mile. If the life of such a fence is 10 years, what is the equivalent annual cost of a 10-mile-long fence at an interest rate of 8% per year? Develop the answer using (a) tabulated factor values, (b) a financial calculator, and (c) spreadsheet functions. (a) A = 3,000,000(10)(A/P,8%,10) 1 30,000,000(0.14903) $4,470,900 (b) If calculator function is PMT(8,10,-30000000,0), the answer is $4,470,884.66 (c) The spreadsheet function - PMT(8%,10,30000000) displays an A of $4,470,884.66 2.17R Recalculate the above problem with an interest rate of 12% per year
