Question 3. (20 pts) Zoltan loves to visit hot springs of Balova Thermal. However, he is not comfortable with paying too much for the one-time daily usage of the hot springs. Therefore, he decided to learn the yearly subscription options of the hot springs. Balova Thermal offered him the following subscription options: one year for 4000 TL, two years for 7400 TL, three years for 10500 TL. These rates, however, are expected to increase due to the inflation. Using the past information, Zoltan calculated the general inflation rate varies between 8% and 11%. Due to lack of engineering economics skills, Zoltan is unable to calculate any further. Help Zoltan to select the optimal strategy that offers a lowest subscription cost, assuming Zoltan will be visiting the Hot Springs for the rest of his life.
