    Answer: x=20.661157; y=484

    Step-by-step explanation:

    (set up a proportion)

    25/120=x/100

    (cross multiply)

    121x=2500

    (divide both sides by 121)

    x=20.661157

    (set up a proportion)

    121/25=y/100

    (cross multiply)

    25y=12100/25

    (divide both sides by 25)

    y=484
