Answer:
<h3>9(7-x) < 36</h3>
Step-by-step explanation:
From the question, we are to relate the amount the teacher spent to the expression 9(7-x).
Since the teacher does not have to spend all the $36, this means that he spent amount less than $36 but not equal to $36. Hence the best inequality sign that relates both expression is a less than sign (<) as shown;
9(7-x) < 36
hence the required inequality is 9(7-x) < 36
