Question

Four students spent $12 dollars on school lunch at this rate find the amount 10 students would spend on the school lunch?

Answer 1

10 students would spend $30.

Explanation:

In order to find this, start by looking for the cost per student. We can do this by dividing the overall cost by the number of students.

$12/4 students = $3 per student.

Now we take that unit rate and multiply by the new number of students.

$3 * 10 students = $30 total spent.
