You start with $500.
First, remove $100. Then remove half of what is left.
How much money do you have at the end?
The correct answer is $200.
Start with:
$500 – $100 = $400
You now have $400 remaining.
Next, remove half of that amount. Half of $400 is $200.
So:
$400 – $200 = $200
That means the final amount is $200.
The key phrase is “half of what’s left.” You do not remove half of the original $500. You first subtract $100, then calculate half of the new balance.
Following the instructions in order makes the puzzle straightforward.
Answer: $200.
