The Komodo Dragon is the largest species of lizard on earth. It is found in a small group of Indonesian Islands and grows to a maximum length of 9.8 ft. They are aggressive, venomous and have septic pathogens in their saliva, which cause bits to become fatal within days. Given the nature of these beasts, they have become a major tourist attraction. Walpole et. al. Conservation Biology (2000) produce estimates of willingness to pay for Komodo National Park visits at $554,864.70 in 2011. Annual operating expenses in 2011 dollars were $344,616.82. Assume the park needs major fence repairs which will occur in year 0 (2011) while the park remains operational which requires loan financing with $50,000 in repayment, annually for 2011-2013. Assume a social discount rate of 7 percent, and an inflation rate of 2.9 percent. Find the following for the time period of 2011 through 2013: 

(a) NVB  

(b) NVC

(c) Present value of net benefitsrn
