You saw a shirt for $97.

You didnít have the cash, so you borrowed $50 from mom and $50 from dad.

50 + 50 = 100

You bought the shirt and had $3 change.

You gave your mom $1 and your dad $1 and kept the other $1 for yourself.

Now you owe your mom $49 and your dad $49.

49 + 49 = 98 + your 1 = 99

Where is the missing $1?
