Question

The senior class plans a school trip to Washington DC. Students should bring money for meals and

souvenirs. They are told to bring at least $60 but no more than $135. Write a compound inequality that
represents the amounts of money a student can bring.

Answer 1

The required inequality is:

`\mathbf{x >60\: and\: x<135}`

Explanation:

Minimum Money students should bring = $60

Maximum Money students should bring= $135

We need to write compound inequality that represents the amounts of money a student can bring.

Compound inequalities are combination of two inequalities combined with "and" , and "or"

And is used, when both inequalities should be true.

Or is used when one of the inequality should be true.

In our case we would use and because we need both inequalities to be true.

The required inequality is:

`\mathbf{x >60\: and\: x<135}`
