Answer:
Bill is correct
Step-by-step explanation:
Bill= 2, 639,456
We have to estimate to nearest ten-thousand
Jill estimation=2,630,000.
Bill got= 2,640,000.
When we have to estimate to nearest ten thousand, than we have to find where the thousand value is greater than 5000 or not
The value is 9456 , which is greater than 5000.
Hence, the correct estimation is 2,640,000
Hence , the bill is correct.
