Here’s what people posted in the comments section of this puzzle:
“The store lost $100. Then they got that $100 back. So far the store has lost $0. But then the store had to return $30 in change. So the store lost probably $30. The store also lost $70 worth of merchandise. So the store ended up losing = $30 in cash + $70 in merchandise = $100 total,” one person posted.
Another commented: “+100 -70 +30 = $60 in the thief’s pocket. Trade: -100 -70 +70 -30 = -130 trade lost in goods and cash combined.”
“The amount of money was 30, but they also lost 70 worth of goods,” remarked a third.
A fourth added: “The store lost a total of $100. Here’s an overview: 1. A man stole $100 from the cash register. This is a $100 loss for the store. 2. He then buys $70 worth of merchandise using the stolen $100. The store receives the $100 bill back, but it is the same bill that was stolen. So there is no profit or loss from this transaction yet. 3. The store gives him $30 in change. This is an additional $30 loss for the trade. Adding up the two losses: $100 (stolen money) + $30 (change) = $130. However, the man also left with $70 worth of merchandise. So the net trade loss when considering the value of goods and money is still $100.”
“There are 3 transactions here. 1. A transaction that led to a $100 bill 2. A transaction that led to a $70 card 3. The difference between the 2 profit margins Really depends on the margins for each individual transaction and the cost to execute all 3 transactions,” shared a fifth.
