Question

A Web music store offers two versions of a popular song. The size of the standard version is  2.9  megabytes (MB). The size of the high-quality version is  4.6  MB. Yesterday, the high-quality version was downloaded three times as often as the standard version. The total size downloaded for the two versions was  4342  MB. How many downloads of the standard version were there?​

Answer 1

260 Downloads

Explanation:

s = number of standard downloads

3s = number of high-quality downloads

2.9s + 4.6(3s) = 4342

2.9s + 13.8s = 4342

16.7s = 4342

s = 260

The standard version was downloaded 260 times and the high-quality version was downloaded 780 times.
