During your class field trip, the teacher plans at a local restaurant and has up to $180 to spend. Which inequality describes the most number of 9.99 meals she can purchase?

Answer 1

Let's say the teacher plans to buy "x" number of $9.99 meals.
Since the teacher has up to $180 to spend, the total cost of the meals cannot exceed $180. Therefore, the inequality that describes the most number of $9.99 meals she can purchase is: 9.99x ≤ 180.
