To determine the inequality that describes the maximum number of Combo B meals the teacher can purchase with a budget of up to $180, we first need to define a variable for the number of Combo B meals.
Let's let \( x \) represent the number of Combo B meals purchased. Each Combo B meal costs $8.99. The total cost for \( x \) Combo B meals would then be \( 8.99x \).
To express the condition that the total cost must not exceed $180, we can set up the following inequality:
\[ 8.99x \leq 180 \]
This inequality describes the maximum number of Combo B meals the teacher can purchase without exceeding the budget.
