What can I do with 40 dollars?
Donate 10% ($4) put 25% ($10) in savings, and you know have $26 to spend. Movies and popcorn maybe?
If you don't NEED it for anything important, definitely donate it
buy a nice dinner :D or save it for something else that is more expensive
depends. i would save it in case u need money or save it for sales
Buy video games
buy mcdonalds then donate to a local charity near you or donate to kids who dont have food
May I suggest you put your money into a savings account?...
Go out to dinner, go see a movie, buy some new books or CDs or clothes :)
