x child tickets
2 x adult tickets

5.90 x + 9.90 ( 2x ) = 771
(5.90 + 19.80)x = 771
25.7 x = 771
x = 30

A Web music store offers two versions of a popular song. The size of the standard version is 
2.4
megabytes (MB). The size of the high-quality version is 
4.3
 MB. Yesterday, the high-quality version was downloaded four times as often as the standard version. The total size downloaded for the two versions was 
5684
 MB. How many downloads of the standard version were there?
