Question

Joey borrows $50 from his mom & $50 from his dad. He buys a coat for $97. With the change he pays back $1 each to his parents and keeps $1. That means he took $49 from each parent equaling $98 + the one he kept = $99. Where did the extra dollar go?

Answer 1

Joey borrowed $50 from each parent and spent $97 on a coat. He got $3 back. He gave $1 to each parent so he borrowed only $49 from each parent and spent $97. He borrowed $98 and spent $97 so he has $1 left that he keeps for himself.

It's $97+$1=$98, not $98+$1.

Answer 2

the $98 = the $97 coat + the $1 he kept
