Solve for the indicated variable.
-$q = \frac { c } { 4 } ( h + r )$ for $r$
A) $r = \frac { q } { 4 c } - h$
B) $r = \frac { 4 q - h } { c }$
C) $r = \frac { 4 q } { c } - h$
D) $r = \frac { 4 c } { q } - h$

To solve for $r$, first multiply both sides by $4$ to get rid of the denominator, resulting in $4q = c(h + r)$. Then, divide both sides by $c$ to isolate $h + r$, giving $ \frac{4q}{c} = h + r$. Finally, subtract $h$ from both sides to solve for $r$, resulting in $r = \frac{4q}{c} - h$.
