Let "w" be the number of weeks it takes for Lily to save up at least $300.
The amount of money she saves each week can be represented as:
$65 (tutoring earnings) + $40 (grandfather's gift) = $105
Therefore, the inequality for the number of weeks would be:
105w + x ≥ 300
where "x" is the amount of money Lily currently has.
The solutions to this inequality will be any non-negative integer "w" that satisfies the equation, since Lily cannot have a non-integer number of weeks. The specific value of "x" will depend on how much money Lily has saved previously or how much additional money she may receive.
