Suppose the college station city council is planning to expand Central Park in College Station, TX. They asked you to advise the city council on whether it will be worth spending tax-payer dollars on park expansion. Suppose the discount rate (r) is 5% and the expected benefits and costs for the next 4 years are provided in the table below.
