for such an easy question , iv had great craic with this one. nearly everyone takes out the fingers to count on them , when that fails they usually get out the pen and paper to write it out . very simple to make a mistake ,lol
I saw a shirt for $97. I borrowed $50 from mom and $50 from dad. I bought the shirt with $3 of change. I gave $1 to mom, $1 to dad, and kept $1 for myself. Now I owe my mom $49 and my dad $49. $49+ $49=$98+my $1=$99. Where did the other $1 go?
$1 didn't go anywhere... it is an accounting question and not a maths / numbers problem.
You have assets and liabilities in an accounting context (which must balance each other out):
step 1 ($100 cash / $100 debt to parents)
step 2 ($97 shirt + $1 in your pocket / $98 owed to parents).
