What's my friend entitled to?

She's working part time ATM what benefits is she entitled to because when she orders a repeat prescription for her mess it's �7 per order and then she has �3/�4 travel expense 3 times a week so she's not got very much left, she's still looking for full time work that's permanent and took the part time job so at least she was Sittin around being a waste and statistic she's 23
