Question

A Web music store offers two versions of a popular song.The size of the standard version is 2.2MB. The size of the high quality version is 4.2MB. Yesterday, there were 1250 downloads of the song, for a total size of 4290MB. How many downloads of the high quality version were there?

Answer 1

Let x= number of standard versions downloaded
1250-x= number of HQ versions downloaded

2.2x+4.2(1250-x)=4290 (in MB )
2.2x+5250-4.2x=4290
2x=5250-4290
2x=960
x=480

There were 480 downloads of the HQ version

Answer 2

Thanks!
