Suppose you own a small company that is contemplating construction of a suburban office block. The cost of buying the land and constructing the building is $$795,000.$ Your company has cash in the bank to finance construction. Your real estate adviser suggests that you rent out the building for two years at $$34,750$ a year and predicts that at the end of that time you will be able to sell the building for $$878,000.$

Thus there are now two future cash flows$--$a cash flow of C$1=$ $$34,750$ at the end of year $1$ and a further cash flow of C$2=($$$34,750+878,000)=$ $$912,750$ at the end of the second year.

a$.$ Calculate the NPV of the office building venture at interest rates of $6,11,$ and $16\%.($Negative amount should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to $2$ decimal places.$)$
