To find the difference in the number of music CDs sold between 2003 and 2013 by the company, follow these steps:
1. Identify the number of CDs sold in each year.
- In 2003, the number of music CDs sold was approximately [tex]\(1.5 \times 10^5\)[/tex].
- In 2013, the number of music CDs sold was approximately [tex]\(7.1 \times 10^7\)[/tex].
2. Convert the scientific notation to standard form for clarity:
- [tex]\(1.5 \times 10^5\)[/tex] is equal to 150,000.
- [tex]\(7.1 \times 10^7\)[/tex] is equal to 71,000,000.
3. Subtract the number of CDs sold in 2003 from the number of CDs sold in 2013:
[tex]\[
71,000,000 - 150,000 = 70,850,000
\][/tex]
4. Thus, the difference in the number of music CDs sold between 2003 and 2013 is 70,850,000.
Therefore, the correct answer is:
B. [tex]$70,850,000$[/tex]
