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?
• 9.99x < 180
• 8.99x > 180
• 8.99x < 180
• 9.99x ≥ 180
The most number of Combo B meals the teacher can purchase can be determined by dividing the total amount of money available ($180) by the cost of one Combo B meal ($9.99).
The correct inequality to represent this situation is 9.99x ≤ 180. This is because the teacher cannot purchase a fraction of a meal, so the number of meals must be less than or equal to the highest whole number that satisfies this equation.
