You have $600. First remove $200, then remove half of what is left. How much money remains?
Answer: $200.
Start with $600 and subtract $200. That leaves $400.
Now remove half of the remaining $400. Half of $400 is $200, so subtracting that amount leaves $200.
The key is the phrase “half of what’s left.” You calculate the half only after the first $200 has already been removed.
Step by step: $600 − $200 = $400, then $400 − $200 = $200.
So the final amount you have is $200.
