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

To solve for $r$, start with the given equation $A = P(1 + nr)$. First, isolate the term containing $r$ by subtracting $P$ from both sides, giving $A - P = Pnr$. Then, divide both sides by $Pn$ to solve for $r$, resulting in $r = \frac{A - P}{Pn}$.
