This money puzzle requires doing the steps in exactly the order they are written. You begin with $400. First, remove $50. Then remove half of what remains.
Answer: $175.
Start with $400 and subtract $50, leaving $350. Now find half of $350, which is $175. The instruction says to remove that half, so $350 − $175 leaves $175.
A common mistake is to take half of the original $400 instead of half of the amount left after removing $50. The phrase “half of what’s left” is the important part. Follow the sequence carefully and $175 is the amount remaining.
