65x + 40 ≥ 300, where x is the number of weeks Lily will need to save. Lily must save for at least 4 weeks to have at least $300.
To find the number of weeks Lily will need to save, we can solve the inequality:
65x + 40 ≥ 300
65x ≥ 260
x ≥ 4
Therefore, Lily will need to save for at least 4 weeks to have at least $300 to buy the cellphone.
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.
