    Answer:

    45 songs in one year (12months)

    Step-by-step explanation:

    in one year she will have the following

    12 x 3 = 36

    + 9 given

    36+9 = 45 songs in one year

    if it was decreasing to 11 months or 10 months etc

    Then we use this formula

    Birthday + (Amount monthly x No of month)

    9 + (3 x 11) = 42 in 11 months

    or 9 + (3 x 10) = 39 in 10 months
