Canadian Metal, Mining, and Petroleum Company is analyzing two projects for possible investment. Only one investment will be made. The first project is an oil drilling project in Alberta at a cost of $510 million that will produce $102 million per year in Years 5 through 10 and $205 million per year in Years 11 through 20. The second project is an expansion of an aluminum smelter in Mapletree, Quebec, and will cost $510 million and will produce $89 million per year for Years 2 through 20. The cost of capital is 10 percent. a-1. Calculate the net present value for each project. (Set calculator to 4 decimal places. Do not round intermediate calculations. Round the final answers to the nearest whole dollar. Enter your answers in whole dollars, not in millions - for example if your answer is 1,000,000 enter 1,000,000 and not 1.)

b-1. If the oil-well project justifies an extra 6 percent premium over the normal cost of capital because of its riskiness and relative uncertainty of flows, recalculate the net present value of the mine. (Round "PV Factor" to 3 decimal places. Negative answer should be indicated by a minus sign. Do not round intermediate calculations. Round the final answer to the nearest whole dollar. Enter your answers in whole dollars, not in millions.)
