Question

How smart are you? A lady walk in the store and steals $100 bill from the register without the owners knowledge. She comes back 5 mins later and buys $70 worth of goods with the $100 bill. The owner gives her $30 in change. How much did the owner lose?

Answer 1

The owner lost $100 ($ 30 cash and $70 worth of goods)

think about it...she stole $ 100.....but then the $ 100 was given back to the store....so she basically exchanged the $ 100 for $ 70 worth of goods and $ 30 cash.

Answer 2

-100-70+100-30=-100

I included the value of the merchandise that she "purchased", so the owner lost $100 in total value.
