Aguy walks in the store and steals 100 without the owners knowledge. he comes back 5 minutes later and buys 70 dollars worth of goods with the 100 dollar bill. the owner gives him back 30 in change

Assuming the question is how much did he lose, it's $100. If we assume he started with $500 in his register, the original $100 stolen lowers it down to $400. The guy buying $70 worth of stuff puts it back to $470 in the register, but now with $70 less merchandise, so he lost $30 in cash and $70 in merchandise.
