Solve the formula for the indicated variable.
-$\mathrm { A } = \mathrm { P } ( 1 + \mathrm { nr } )$, for $\mathrm { r }$
A) $r = \frac { A - P } { P n }$
B) $r = \frac { P n } { A - P }$
C) $r = \frac { P - A } { P n }$
D) $r = \frac { A } { n }$

To solve for $r$, first subtract $P$ from both sides to get $A - P = Pnr$. Then, divide both sides by $Pn$ to isolate $r$, resulting in $r = \frac{A - P}{Pn}$.
