Problem 3: "The Highway Fee Tracking Software Case" The Haverty County Transportation Authority (HCTA) has just installed a new software to charge and track toll fees. This new software will be used for the indefinite future. Therefore, the director wants to know the total equivalent present worth of the expected transactions listed as follows: The system has an initial installation cost of $100,000. There is a one-time additional cost of $70,000 due in year 6. The annual software maintenance cost is $5,000 for the first 4 years, and then $7,000 thereafter. In addition, there is expected to be a recurring major upgrade cost of $12,000 every 10 years. The interest rate is of 15% per vear for county funds. a) Draw the cash flow diagram for at least the first 20 years of operation. b) Formulate the total equivalent present worth of the entire transaction scenario using economy factors. DO NOT EVALUATE (Hint: Use the capitalized cost formula: P = A/i when needed) Problem 3: "The Highway Fee Tracking Software Case" The Haverty County Transportation Authority (HCTA) has just installed a new software to charge and track toll fees.
