Answer 1

The company purchased about 20 million more spools of thread in 2007 than in 2005, after rounding to the nearest ten million.

Step-by-step explanation:

To find out how many more spools of thread the company purchased in 2007 than in 2005, we subtract the number of spools purchased in 2005 from the number of spools purchased in 2007. That calculation is as follows:

2007 purchases: 58,239,548
2005 purchases: 37,388,947
Difference: 58,239,548 - 37,388,947 = 20,850,601 spools

Now, to round this to the nearest ten million, we look at the first digit of the millions place. Since the digit is a 0 (20,850,601), we do not round up, and our rounded number remains 20 million spools.

Therefore, the company purchased about 20 million more spools of thread in 2007 than in 2005.
