It will take one year to construct it$,$ requiring an investment of $$9\mathrm{.}78$ million today and $$5$ million in one year. The government will pay you $$22\mathrm{.}5$ million upon the building's completion. Suppose the cash flows and their times of payment are certain, and the risk$-$free interest rate is $11\%.$
