Lets think about this... You didnt mention a store so i will assume this is a chain store. Chain stores generally operate on small margins of profit of 1%.



Of the original $100 that was stolen only 1% of that was profit ($1) and the other 99% ($99) would have been used to repay the inherent costs. The stores original loss would have only been $99.



When the theif returns and spends $70. The stores profit is $0.70 and the inherit costs are $67.30. Even though the money was stolen from the store, it still turns a $0.70 profit from the sale.



We subtract the profit from from the second sale ($0.70) from the original inherent cost from the first ($99) and the actual loss for the store is...



98.30

Thats a smart cat at the register trying to minimize losses .

$100 when he stole it + $ 70 in merchandise & $30 cash back . So $200 in total.

Me think the store lost about $70.



$100 - $30 = $70, which is the amount of change the man received.

Although the Man spent $70 at the store, the didnt lose that amount of money considering the fact thst they received payment for the items purchased.

Is 100$ the right answer?
