A man stole $ 100 from a store cashier, without the owner noticing. Five minutes later, he returned and bought $ 70 in clothing, using the same $ 100 bill. The owner returned R $ 30.00 of change. How much did the store owner lose?
If the man stole $ 100.00, the store owner lost $ 100.00, this is the answer.
Note that later the stolen $ 100 returned to the store as if it were a purchase of products. Thus, the man got back the $ 100.00, but lost the $ 30.00 that gave change plus clothes in the amount of $ 70.00, so adding $ 30 + $ 70, 00 we arrived at the same $ 100.00.
Obs: The statement leaves room for other interpretations, so even other answers can be accepted.
