Because it is clear that you are in higher tax bracket than your daughter it more beneficial for you to claim her as a dependent.
If you claim her as dependent you will have $3200 extra deduction that with your 25% taxes will save $800
Your daughter will lost $3200 deduction and will pay $981 instead of $578 - that ~$400 extra taxes
The saving is about $400.
There might be other things that should be taken in consideration, such as if she is your dependent and you takes a loan to pay for college - you will be eligible to deduct the educational expenses and interest whet the time comes to pay it back.
You daugher can not claim her educational expenses because you CAN claim her as a dependent. It doesn't matter for this situation if you actually claim her or not. The only way to get tax benefits for educational expenses is to claim them on your return.
