Question

Someone came into my shop and stole $100 out of the register without my knowledge. The person came with the same $100 5 minutes later and he bought $70 in Items and I gave him back $30 change. How much money did I loose!!!!!!

Answer 1

This can be solve using money balance, money balance concept is you add to your account the money that goes in to your account and subtract the money that goes out.

Net money = money in – money out

Net money = (100) –(100-30) = - $ 30

You lost $30 money not including the goods he bought by the stolen money
