An oil-drilling compary must choose between two mutually excluswe extraction projects, and each requires an initial outlay at t=0 of $12.4 million. Under Plan A, all the ofl would be extracted in 1 year, producing a cash flow at t=1 of $14,88 million. Under Plan B, cash flows woutd be $2.2034 million per year for 20 years: The firm's wacC is 13%. a. Construct NPV profiles for Plans A and B. Enter your answers in millions. for example, an answer of $10,550,000 - should be entered as 10.55 , If an amoune is zero, enter 00. Negative values, if any, should be indicated by a minus sign. Do not round intermediate calculations, Round your answers to two decimal places. Wentily each broject's 18R. Do not round intermediate calculations. Round your an uwers to twe decimal places: hojed A : Nojed B: b. Is it logical to assume that the firm would take on all avalable independent, average-risk profects with returns greater than 13% ?
