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
The inequality is x + (40 + 65x) ≥ 300, where x is the number of weeks Lily will need to save. Lily must save for at least (300 - 40) / (65 + 1) = 4.23 weeks to have at least $300.
What are the answers I should put in
The solution to the inequality is x ≥ 4.23.
However, since the number of weeks cannot be a fractional value, Lily would need to save for at least 5 weeks to have at least $300.
