It's very confusing. One of my friend ask me about this question. It seems like very easy to answer but in the end you will be confuse which is which. So here's the qeustion.
Ana went out with his older brother and older sister. They went to department store for shopping. After a lot of shopping, she saw this beautiful dress. She like to buy it but she was already short of money. The dress is worth $97(assuming). What she did for her to be able to buy that, she borrow $50 to his brother and $50 to her sister. So she got now a total of $100. She bought the dress worth $97 and her money is $100. So she still has $3 left as change for the $100. She give back each $1 to his brother and $1 to her sister in which now she owe's only $49 each of them. Both total $98. she still have $1 left on her hands when she give the $2. In which would make a total of $99 only( $98+$1). It's supposed to be $100 because that was her money..so where is the $1? Whats your answer can you tell me?

In fact, there is no money missing. Just need some conceptual change only :)
So, Anna is actually borrowing 2*($50-$1) = $98 from his brother and sister. He bought the dress for $97 so she still have ($8-$97) = $1. Which is correct.
Also, we can say that Anna borrowed $100. She paid $97 and left with $3. At this time, the $3 is considered hers (Just that she use $2 pay back the debt) So it should be $100. After she paid the debt, her total debt become $98 and no longer $100. That's how she had bought the dress ($97), with $1 change and still owe her bro & sis $49 each.
Hope this solve your doubt :)
