Answer 1

Sherman is correct because the total units sold, according to his claim (2 x 10^9), matches the given number of total music units sold in one year.

Step-by-step explanation:

To determine if Sherman is correct, we can calculate the total number of music units sold based on his claim and compare it to the given number. Sherman claims that the total number is about 4 x 101 times the number of digital albums sold.

Let's calculate this:

• Number of digital albums sold: 5 x 107 units
• According to Sherman: total units sold = 4 x 101 x (5 x 107)
• Total units sold according to Sherman = 2 x 109 units

Since this is the same as the given number of total music units sold in one year, Sherman is correct.
