Let's solve this problem together! We know that the size of the standard version is 2.2 MB and the size of the high-quality version is 4.3 MB. Yesterday, there were 880 downloads of the song, and the total download size was 3196 MB.
To find the number of downloads of the standard version, we can set up an equation. Let's call the number of downloads of the standard version "x".
The equation would be:
2.2x + 4.3(880 - x) = 3196
Now, we can solve this equation to find the value of "x", which represents the number of downloads of the standard version.
