Question

There are 200 students but 30% of students who purchase milk with their lunch pick strawberry milk. If 36 students purchase strawberry milk, how many total students buy milk with their lunch?

Answer 1

We know that 36 students make up 30 percent of all students who pick milk. We need to find the total number of students who pick milk. Let's solve for this total, t:
$t(0.30) = 36 \\ t = \frac{36}{0.30} \\ t = 120$

There are 120 students that pick milk with their lunch.

 ↓     ↓                     ↓                     ↓           ↓

0.3    *                       x                    =           36

0.3x =  36

÷0.3    ÷0.3

    x  =  120
