A second politician says to you, At an interest rate of 6%, the project is a bad idea. Over 10 years, the project reduces maintenance costs by a total of $3 billion. But borrowing $2 billion for 10 years at a 6% interest rate means paying $1.58 billion in interest. The total cost of the project over 10 years is, therefore, $3.58 billion! Use present value calculations to show that the project is, in fact, worth undertaking at a 6% interest rate. Whats wrong with the second politicians argument?
