Answer:
<u>There were 560 high-quality version downloads of the song yesterday</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Size of the standard version = 2.7 MB
Size of the high-quality version = 4.9 MB
Number of downloads of the song yesterday = 1,440
Download size yesterday = 5,120 MB
2. How many downloads of the high-quality version were there?
For answering the question we will use the following equation:
x = Number of high-quality downloads of the song yesterday
1,440 - x = Number of standard downloads of the song yesterday
Number of high-quality downloads of the song yesterday * Size of the high-quality version + Number of standard downloads of the song yesterday * Size of the standard version = Download size yesterday
Replacing with the real values, we have:
4.9x + (1,440 - x) * 2.7 = 5,120
4.9x + 3,888 -2.7x = 5,120
2.2x = 5,120 - 3,888
2.2x = 1,232
x = 1,232/2.2 = 560
x = 560 ⇒ (1,440 - x) = 880
<u>There were 560 high-quality version downloads of the song yesterday and 880 standard version.</u>
