Final answer:
The right answer is A, which is 53% of Album 1 copies were sold as CDs, 49% of digital downloads sold were Album 2, and Album 1 had a higher percentage of sales as digital downloads than Album 2.
Step-by-step explanation:
To solve the student's question, we need to find the percentage of copies sold as CDs for album 1, the percentage of digital downloads sold that were for album 2, and compare the percentage of digital downloads sold between the two albums.
First, let's calculate the percentage of Album 1 copies sold as CDs:
- Total copies of Album 1 sold = CD sales + Digital downloads = 540 + 470 = 1010.
- The percentage of Album 1 sold as CDs = (CD sales for Album 1 / Total copies of Album 1 sold) × 100% = (540 / 1010) × 100% ≈ 53.47%, which we can round to 53%.
Next, we will calculate the percentage of digital downloads that were of Album 2:
- Total digital downloads sold for both albums = Digital downloads for Album 1 + Digital downloads for Album 2 = 470 + 452 = 922.
- The percentage of digital downloads that were for Album 2 = (Digital downloads for Album 2 / Total digital downloads) × 100% = (452 / 922) × 100% ≈ 49.02%, which we can round to 49%.
Finally, we will determine which album sold a higher percentage as digital downloads:
- Percentage of Album 1 sold as digital downloads = (Digital downloads for Album 1 / Total copies of Album 1) × 100% = (470 / 1010) × 100% ≈ 46.53%.
- Percentage of Album 2 sold as digital downloads = (Digital downloads for Album 2 / Total copies of Album 2) × 100% = (452 / (571 + 452)) × 100% ≈ 44.19%.
Album 1 has a higher percentage of digital downloads sold than Album 2. Therefore, the correct answer is A. 53%, 49%, 1, 2.
