To find the number of weeks Lily will need to save, we can represent the information given with an inequality. Let's say the number of weeks Lily needs to save is represented by the variable x.

We know that Lily's grandfather gave her $40 and she earns $65 tutoring each week. So, the total amount of money Lily will have after x weeks is 40 + 65x.

We want to find the minimum number of weeks Lily needs to save to have at least $300. So, our inequality would be:
40 + 65x ≥ 300

To solve this inequality for x, we can subtract 40 from both sides of the inequality:
65x ≥ 260

Then, divide both sides of the inequality by 65:
x ≥ 4

So, Lily needs to save for at least 4 weeks to have at least $300.
