Question 1167968: A Web music store offers two versions of a popular song. The size of the standard version is 2.3 megabytes (MB). The size of the high-quality version is 4.1 MB. Yesterday, there were 1220 downloads of the song, for a total download size of 3598 MB. How many downloads of the standard version were there? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! std is S
high is H
S+H=1220, H=1220-S
2.3S+4.1(1220-S)=3598
-1.8S+5002=3598
-1.8S=-1404
S=780@2.3=1784
H=440@4.1=1804
780 is the answer
