Missing dollar problem This sounds silly but I saw this and I couldn't figure it out so I thought you could help.
The below is what I saw.
You see a top you want to buy for $\$97$, but you don't have any money so you borrow $\$50$ from your mom and $\$50$ from your dad.  You buy the top and have $\$3$ change, you give your mom $\$1$,your dad $\$1$, and keep $\$1$ for yourself.  You now owe your mom $\$49$ and your dad $\$49$.
$\$49 + \$49 = \$98$ and you kept $\$1$.   Where is the missing $\$1$?

Accountability...
total debt= 100 USD
Top= 97 USD
Debt to your mom= 48.5 USD + pay back to her 1 USD = 49.5 USD
Debt to your dad= 48.5 USD + pay back to him 1 USD = 49.5 USD
Debt both of them (still in your pocket)= 1 USD
Total = 100 USD
No dollar missing.
