For each of the following situations involving single amounts, solve for the unknown. Assume that interest is compounded annually. $(i=$ interest rate, and $n=$ number of years$)$

Note: Use tables, Excel, or a financial calculator. Round your final answers to nearest whole dollar amount. $($FV of $$1,$ PV of $$1,$ FVA of $$1,$ PVA of $$1,$ FVAD of $$1$ and PVAD of $$1)$
