a. Economists in the ministry of agriculture in Kwale County have estimated the following market model for fertilizer based on annual time series data on price and quantity in thousands. The government intends to reduce the market price by 20% per bag as requested by the farmers. Consequently, it will buy the excess output if any at the market equilibrium price. Alternatively a new plant costing 20 million with a life time of five years, producing 5million worth of fertilizer annually can be constructed. Assuming a 10% market rate of return, what should the county government do?
