Question

scenario: the number of students in each classroom must be under 30. inequality: (blank). number line: (number line with 22,24,26,28,30,32,34,36,38,40 marked)

Explanation:

Step1: Define the variable

Let \( s \) represent the number of students in each classroom.

Step2: Formulate the inequality

Since the number of students must be under 30, the inequality is \( s < 30 \).

Step3: Graph the inequality on the number line

• Draw an open circle at 30 (because 30 is not included, as the number must be under 30).
• Shade the region to the left of 30 on the number line (since \( s \) is less than 30).

Answer:

Inequality: \( s < 30 \)
Number line graph: Open circle at 30, shading to the left.
