An oil$-$drilling company must choose between two mutually exclusive extraction projects, and each requires an initial outlay at t $=0$ of $$12$ million. Under Plan A$,$ all the oil would be extracted in $1$ year, producing a cashflow at t $=1$ of $$14\mathrm{.}4$ million. Under Plan B$,$ cash flows would be $$2\mathrm{.}1323$ million per year for $20$ years. The firm's WACC is $12\mathrm{.}8\%.$

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 $10\mathrm{.}55.$ If an amount is zero, enter $"$O$".$ Negative values, if any, should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to two decimal places.
