Answer
$p$ varies directly as $q$, $r$, and $t$ and inversely with $s$.
Work Step by Step
Recall:
For an equation of the form $y=\frac{kwxy}{z}$, $y$ varies:
(1) directly with the variable in the numerator; and
(2) inversely with the variable/s in the denominator.
Thus, in the given variation, $y$ varies directly as $q, r, \text{ and } t$ and inversely with $s$.
