"The gaseous coal is then burned in a gas turbine cycle and part of the residual heat from the exhaust gases is recovered to generate steam for the steam turbine. Currently, the construction of such plants costs about $ 1500 per kW, but their efficiency is about 45%. The average calorific value of coal is about 28,000,000 k J per ton (that is, 28,000,000 k J of heat released when 1 ton of coal is burned). If the mill is to recover its cost difference in five years from fuel savings, determine what the price of coal should be in $ per ton?"
