Problem 2 Waller County is planning to construct a Multi-million dollar Recreation and Museum centers some tens of miles away from Prairie View A \& M University to facilitate Tourism in the City of Prairie View. The first cost for the center will amount to $15,000,000. Annual maintenance and repairs will amount to $55,000 for each of the first six years, to $65,000 for each of the next twelve years, and to $70,000 for each of the next six years. At the end of the 24th year, $50,000 is estimated to be deposited into Waller county account as tax credits eamed for its environmental compliance in the construction and operation of the center. In addition a major overhaul costing $850,000 will be required at the end of the thirteenth year. Use an interest rate of 7% and determine: a) Determine the engineering economy symbols and their value for each option. b) Construct the cash flow diagram c) Determine the total Annual Worth for the Project d) What is the Future worth of this project Problem 2 Waller County is planning to construct a Multi-million dollar Recreation and Museum centers some tens of miles away from Prairie View A \& M University to facilitate Tourism in the City of Prairie View.
