If Mike buys his lunch at school, it costs him $2.75 per lunch. If Mike takes the bus to school, it costs him $1.50 per bus ride. He tries to spend no more than $50 on these options each month. Let x represent the number of lunches that Mike buys in school and let y represent the number of bus rides that he takes. Given the following two inequalities below, what is the third inequality that represents Mike's situation?

𝑥 ≥ 0

𝑦 ≥ 0

__________________________

• x + y ≤ 50
• 2.75x + 1.50y ≤ 50
• x + y > 50
