Deductions & credits

I guess I still need help with the following questions (with the situation describe above):

 

-My daughter has paid for both airfare tickets, can she deduct her mother's portion (on Schedule C)?

-My daughter has paid for both meals during travel, can she deduct her mother's meal portion?

-My wife pays for the rental car, can my daughter deduct the rental car expense? If not, if my daughter pays for the rental car while her mother drives the car (not sure if this is acceptable to the rental car company), then, is the rental car can be deducted?

 

Thanks
