Question

Mr. Jones needs at least 1 gallon of punch for every 16 students at the school dance. He has 8 gallons of punch. The inequality below represents this situation, where x is the number of students that can be served.





x
16
≤
8


What is a reasonable number of students who can be served with 8 gallons of punch?

Answer 1

Solve x/16 ≤ 8. Multiply both sides by 16: x ≤ 128.

So with 8 gallons he can serve at most 128 students. A reasonable number is 128 students.
