65x + 40 ≥ 300, where x is the number of weeks Lily will need to save. Lily must save for at least 3 weeks to have at least $300.

The inequality represents the amount of money Lily earns from tutoring after school each week (65x) plus the amount of money her grandfather gave her (40) is greater than or equal to 300. The solution to the inequality gives the minimum number of weeks Lily needs to save in order to have at least $300.
