Solve Combined Variation Problems
-$p$ varies directly as $q$ and inversely as $r$.
A) $\mathrm { p } = \frac { \mathrm { kq } } { \mathrm { r } }$
B) $p = \frac { k r } { q }$
C) $\mathrm { pqr } = \mathrm { k }$
D) $\mathrm { p } + \mathrm { q } - \mathrm { r } = \mathrm { k }$

Question

Quizplus · Accepted Answer

The correct formula for $p$ varying directly as $q$ and inversely as $r$ is $p = \frac{kq}{r}$, where $k$ is the constant of proportionality. This captures both the direct variation with $q$ and the inverse variation with $r$.
