Let, Nia's allowance = x
For book = 2x/5
Remaining = 3x/5
Shirt = 2/3 of remaining amount = 2/3 * 3x/5 = 2x/5
So, total exp = 4x/5
Remaining = x/5 = 7
x = 35.

Hope charmaine.chua got my point! :D
Correct me If I am wrong

ummm sometimes when I read this kind of problem, I feel it's too easy to be true, but here is what I think:

x being her daily allowance we have the following equation:

x-(2/5*x+2/3*(3/5*x))=7 which gives x=35. ?
