Problem $7-34$

A bottle of $10-$year$-$old Scotch whisky sells for $$40.$ A bottle of $17-$year$-$old Scotch whisky sells for $$89.$ The cost to age a bottle of whisky $($use of barrels, storage space, labor, etc.$)$ costs $$3/$ year. If you own a distillery and can "invest" $10-$year old bottles to grow them into $17-$year old bottles, what is your annual rate of return? Use Appendix $D$ to answer the question. Round your answer to the nearest whole number.
