Okay...I've never been good at math or word problems, but I came across a situation today that is really bugging me. Can anyone help? Here's the situation:
Lunch costs $5. Steve, Dave, and John are all having lunch from the same place. So, Dave borrows $10 from his office's petty cash for lunch. Steve puts in another $10 to cover his lunch, and Jack puts in $5 for himself. (Jack now has $25 for 3 lunches, which total $15.) Dave replaces the $10 that he borrowed petty cash. Dave got no change back, so is he getting ripped off? Dave is told that he gets no change because he started out with nothing anyway.
I say that he is, but I could be totally off base. I'm so confused!!!!!!!!!
