Answer :

If your answer is $200 or $130 loss, read on below for the correct answer and explanation.

The correct answer is the Store loss $100, or a more technical
answer is the Store loss $30 + buying cost of the $70 goods.

Let’s go through the question and see how the answer is derived.

“A guy walks into a store and takes a $100 bill from the register
without anyone’s knowledge.”    <– The Store loss $100

“He then buys $70 worth of goods using the $100 bill and receives
$30 back in change.”    <– This is where most people makes the
mistake of adding on to the initial $100 loss. The Store does not
make any loss on this transaction.

Explanation :

The 2nd sentence is a normal transaction where the store does not
make any additional loss, hence the loss is $0. Therefore, when we add
both losses up, it becomes -100 + 0 = -100

The more technical answer is that the Store loss $30 + buying cost
of the $70 goods.
