To create an inequality that describes the maximum number of Combo B meals the teacher can purchase within a budget of $180, we need to know the cost of one Combo B meal. Let's denote the cost of a Combo B meal as \( p \) (in dollars) and the number of Combo B meals purchased as \( x \).
The inequality representing the situation will be:
\[ p \cdot x \leq 180 \]
Where:
- \( p \) is the price of one Combo B meal,
- \( x \) is the number of Combo B meals she can buy,
- \( 180 \) is the total budget.
Rearranging the inequality to express it in terms of \( x \), we get:
\[ x \leq \frac{180}{p} \]
To summarize, the inequality which describes the maximum number of Combo B meals the teacher can purchase, given the price \( p \) of each meal, is:
\[ x \leq \frac{180}{p} \]
Make sure to substitute the actual price of Combo B meals into the inequality to get a numerical answer.
