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

To solve for $r$, first isolate the term containing $r$ by subtracting $P$ from both sides: $A - P = Pnr$. Then, divide both sides by $Pn$ to solve for $r$: $r = \frac{A - P}{Pn}$.
