I did the same for my 15 yr old way back when. What are your expenses, how much do you need to cover expenses, how many hours can you work= how much per hour do you need to earn. In 1996 she needed to earn $12.75 per hr to live the way she wanted. That was with roommates helping on rent. Minimum wage was much less, so it was my argument for good grades to get a good job.
The plot must have conflict and change or we wouldn’t be reading it. I hope Luann moves into something with more options so she will be centric to the story line again.
Now Tom will insist Tiff live in the dorm.
