Final answer:
Warren's salary will be $93,750 after the 25% cut and 25% raise.
Step-by-step explanation:
Warren's salary will be reduced by 25% initially. This means his salary will become $100,000 - (0.25 * $100,000) = $75,000.
Then, Warren's salary will be increased by 25%. This means his salary will become $75,000 + (0.25 * $75,000) = $93,750.
So, Warren's salary will be $93,750 after the 25% cut and 25% raise.
