You have $500. First remove $100, then remove half of what is left. How much money remains?
Answer: $200.
Start with $500 and subtract $100. That leaves $400.
Now remove half of the remaining $400. Half of $400 is $200, so subtracting that amount leaves $200.
The key phrase is “half of what’s left.” You calculate the half only after the first $100 has already been removed.
Step by step: $500 − $100 = $400, then $400 − $200 = $200.
So the final answer is $200.
