An auto plant that costs $100 million to build can produce a line of flex-fuel cars that will produce cash flows with a present value of $140 million if the line is successful but only $50 million if it is unsuccessful. You believe that the probability of success is only about 50%. You will learn whether the line is successful immediately after building the plant. a-1. Calculate the expected NPV. Note: Do not round intermediate calculations. A negative amount should be indicated by a minus sign. Enter yourkinswer in millions. a-2. Would you build the plant? Suppose that the plant can be sold for $95 million to another automaker if the auto line is not successful. b-1. Calculate the expected NPV. Note: Do not round intermediate calculations. A negative amount should be indicated by a minus sign. Enter your answer in millions rounded to 1 decimal place. b-2. Would you build the plant
