    Well very interesting question she saves for 17 months.

    Let us see!

    Step-by-step explanation:

    Represent per month saving with 20n. where n is number of months.

    she withdraw $60 so

    = 20n-60

    She now has $280, thus above equation becomes

    280 = 20n-60

    280+60=20n

    340/20=n

    n=17
