Jazz and blues recordings accounted for 6 percent of the $840 million

We are given that the revenue from the sales of jazz and blues in 2000 accounted for 0.06 x (840 million) = 50.4 million dollars in revenue. We need to determine the revenue from the sales of jazz and blues in 1998.

Statement One Alone:

Jazz and blues recordings accounted for 5 percent of the revenue from the sales of recordings in Country Y in 1998.

Since we do not have any information about the total revenue in 1998, statement one alone is not sufficient to answer the question. We can eliminate answer choices A and D.

Statement Two Alone:

The revenue from the sales of jazz and blues recordings in Country Y increased by 40 percent from 1998 to 2000.

Using the information given and statement two, we can determine the revenue from sales of jazz and blues in 1998. If we let the revenue from sales of jazz and blues in 1998 = R, we can create the following equation:

1.4R = 50.4 million

R = (50.4 million)/1.4

R = 36 million

Statement two alone is sufficient to answer the question.

Answer: B
