    Answer:

    Pam: $181

    Amanda: $362

    Julie: $452

    Step-by-step explanation:

    (What does Mike have to do with this problem?)

    Let a = Amanda’s pay

    Let p = Pam’s pay

    Let j = Julie’s pay

    “Amanda made twice what Pam earned”

    a = 2p

    “Julie made $90 more than Amanda”

    j = a + 90

    j = 2p + 90

    Pam earned p

    Total salary

    a + p + j = 2p + p + 2p + 90

    Total salary

    $995

    2p + p + 2p + 90 = 995

    5p = 905

    p = 181

    a = 2p = 2(181) = 362

    j = 2p + 90 = 362 + 90 = 452

    Answer:

    Pam: $181

    Amanda: $362

    Julie: $452
