If you saw a tablet that you really like that is on sale for $97 but don't have the money to buy it, you can borrowed the money from Josh and Mary to pay for it. Suppose you take $50 from Josh and $50 from Mary. That's $100 total. You pay the tablet and the cashier give your $3 change back. You decide to keep a dollar for yourself and repay Josh a dollar and Mary a dollar. You now owe Josh and Mary forty-nine buck each. Forty-nine x two = ninety-eight dollars plus the dollar you keep. So that's ninety-nine buck. Where is the other dollar?
This is a riddle with word play.... Let's first rephrase Gracified23 post.. You borrowed $50 from Josh and Mary and paid for the Tablet that's $97. You paid the tablet but got $3 back... you gave $1 each back to Josh and Mary. You kept $1 for yourself.
This is how you account for the money: Since you gave $2 back to Josh and Mary, you actually only borrow $98 from them.
This is what you owe... you owe Josh and Mary $49 each, that equal $98. Since the tablet cost $97 which you paid for but you kept $1. The Tablet plus what you have equal $98, which is what you owe both Josh and Mary. No money is lost and no extra $1 to talk about.
