Answer: 8000
Step-by-step explanation
The first "9" is in the hundreds place value.
The next digit over is 5. Since this value is 5 or larger, we will bump the 79 up to 80. The rest of the digits become 0s.
7959.9 rounds to 8000 when rounding to the nearest hundred.
The number 7959.9 is closer to 8000 than it is to 7900.
