Question 3

A Web music store offers two versions of a popular song. The size of the standard version is 2.6
megabytes (MB). The size of the high-quality version is 4.4
MB. Yesterday, the high-quality version was downloaded twice as often as the standard version. The total size downloaded for the two versions was 2622
MB. How many downloads of the standard version were there?

Answer 1

Let the following denote:
s = number of standard downloads
2s = number of high-quality downloads 2.6s + 4.4(2s) = 2622
2.6s + 8.8s = 2622
11.4s = 2622
s = 230
The standard version was copied 230 times and the high-grade type was downloaded 460 times.
