Lily is saving up to buy a cellphone. She needs to save at least $300 before she is able to buy the phone. Her grandfather gives her $40, and she earns $65 tutoring after school each week. Write an inequality for the number of weeks Lily will need to save to have at least $300, and describe the solutions.(2 points) x ≥, where x is the number of weeks Lily will need to save. Lily must save for at least weeks to have at least $300.
Inequality: 65x + 40 ≥ 300
x ≥ (300 - 40) / 65
x ≥ 4.31
Solution: Lily must save for at least 5 weeks (since she can't have a fraction of a week) to have at least $300.
