    Answer:

    880 high-quality version

    Step-by-step explanation:

    I think the below is your full question:

    A Web music store offers two versions of a popular song. The size of the standard version is 2.1megabytes (MB). The size of the high-quality version is 4.5 MB. Yesterday, there were 1290 downloads of the song, for a total download size of 4821 MB. How many downloads of the high-quality version were there?

    Here is my answer:

    Let x is the number of high-quality version

    So the number of standard version= 1290 – x

    We also know:  total download size of 4821 MB. which means:

    4.5x + 2.1(1290-x) = 4821

    <=> 4.5x+2709-2.1x=4821

    <=> 2.4x=2112

    <=> x=880

    So there were 880 high-quality version
