Question

jack studies 3 and a half hours each night. if jack wants to calculate how many total hours he studies, what equation should he use for the proportional relationship? enter the answer check it

Explanation:

Step1: Define variables

Let $t$ = total study hours, $n$ = number of nights.

Step2: Set up proportional equation

Jack studies $3.5$ hours per night, so total hours equal hours per night times number of nights.
$t = 3.5n$ or $t = \frac{7}{2}n$

Answer:

$t = 3.5n$ (or $t = \frac{7}{2}n$)
