GPT-4o mini · Answer

The correct inequality that can be used to solve the problem is:

10w + 213 ≥ 299, where w is the number of weeks.

This inequality reflects that the total amount Ellie will have saved after $ w $ weeks (which is her current savings of $213 plus $10 for each week) must be at least $299.
