Lincoln Park Zoo in Chicago is considering a renovation that will improve some physical facilities at a cost of \(\$ 1,800,000\). Addition of new species will cost another \(\$ 310,000\). Additional maintenance, food, and animal care and replacement will cost \(\$ 145,000\) in the first year, increasing by 3 percent each year thereafter. The zoo has been in operation since 1868 and is expected to continue indefinitely; however, it is common to use a 20-year planning horizon on all new investments. Salvage value on facilities after 20 years will be 40 percent of initial cost. An estimated 1.5 million visits per year are made to the zoo, and 2 percent of the visitors per year will perceive an additional benefit of \(\$ 3\) per visit due to the renovation, while 8 percent will perceive an additional benefit of \(\$ 2,20\) percent perceive \(\$ 1\), and 70 percent perceive no additional benefit. Suppose an incremental fee is charged for entrance to the renovated area. Determine the annual financial gain or loss if the fee charged per visit is

a. \(\$ 0.50\).

b. \(\$ 1.50\).

c. \(\$ 2.50\).

d. \(\$ 5.00\)
