Let w represent the number of weeks Lily needs to save before she has at least $300.
The inequality representing this situation is:
65w + 40 ≥ 300
To find the number of weeks Lily needs to save, we solve for w:
65w + 40 = 300
65w = 300 - 40
65w = 260
w = 260 / 65
w = 4
Therefore, Lily will need to save for at least 4 weeks to have at least $300.
Lily is saving up to buy a cell phone. 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.
