During your class field trip, the teacher plans to stop at a local restaurant and has up to $180 to spend. Which inequality describes the most number of Combo B meals she can purchase?

Let's assume the teacher wants to purchase the Combo B meals, which cost x dollars each. We need to find the maximum number of Combo B meals she can purchase with up to $180.

The cost of each Combo B meal is x dollars, and the teacher has $180 to spend.

We can write this as the inequality:

x ≤ $180

Therefore, the inequality that describes the most number of Combo B meals the teacher can purchase is x ≤ 180.
