$\displaystyle \text{For Reference: }$

$\displaystyle P = \text{Present Worth}$

$\displaystyle F = \text{Future Worth}$

$\displaystyle A = \text{Annuity}$

$\displaystyle \text{Example of using the mnemomic expressions is below, }$

$\displaystyle (\frac{A}{P}, i\%,N) \equiv \text{ A constant that when multiplied with the present worth, will provide the equivalent annuity over N peroids given a discount rate of i}\%$

$\displaystyle \text{Similiarly for the other mnemomic expressions.}$

See figure attached for problem statement.

See 2nd figure in 2nd post for my attempt at the problem.
