Please draw cash flow diagrams and solve the following problems with mathematical equations and with interest factor tables A design-construct-operate (DSO) company signed a contract to operate certain industrial wastewater treatment plants for 10 years. The contract will pay the company S2.5 million now and amounts increasing by S250,000 each year through year 10. At an interest rate of 10% per year, what is the present worth (year 0) of the contract to the DSO company? ($25.12043 million) 2. Expenses associated with heating and cooling a large manufacturing facility owned by Nippon Steel are expected to increase according to an arithmetic gradient. If the cost is $550,000 now (i.e., year 0) and the company expects the cost to increase by $40,000 each year through year 12, what is the equivalent annual worth in years 1-12 of the energy costs at an interest rate of 10% per year? ($846,240.7)
