Alright, let’s break this down step by step and uncover the mystery behind the “missing dollar”!
You saw a shirt for $97—a great find! So, you borrowed $50 from mom and $50 from dad. That gives you a total of $100. You buy the shirt and, lo and behold, you get $3 in change.
Now, here’s where it gets a little tricky:
You decide to give $1 back to mom, $1 back to dad, and you keep $1 for yourself. So far, so good! You’re now down to owing $49 to each of your parents.
Now, the puzzle says $49 + $49 = $98, and then adds that $1 you kept, bringing the total to $99. Hold up! You’re wondering: where’s that last dollar?
Here’s the twist: The $98 you owe already includes the $1 you kept for yourself! Let’s put it into perspective:
The $98 is your remaining debt after you returned $1 to each parent.
$97 is the cost of the shirt.
The $1 you kept is embedded in that remaining balance.
So, adding that $1 you kept to the $98 you owe creates a misleading equation. Instead of $98 + $1, you should just focus on the $98—which includes the $97 for the shirt and the $1 you’ve kept for yourself.
There’s no missing dollar! It’s all about how the numbers are framed. The dollar you “kept” is part of the $98 you still owe, not something to add on top.
The real moral of the story? Sometimes the trick isn’t about what you’re missing—it’s about how the question is framed. Now that you’ve solved the puzzle, it’s all clear!
