    Let's use the "brute force" method.

    Start at the top with the most valuable combination and start adding.
    25 + 25 + 25 = 75
    25 + 25 + 10 = 65
    25 + 25 + 5 = 55
    25 + 25 + 1 = 51
    25 + 10 + 10 = 45
    25 + 10 + 5 = 40
    25 + 10 + 1 = 36
    10 + 10 + 10 = 30
    10 + 10 + 5 = 25
    10 + 10 + 1 = 21
    10 + 5 + 5 = 20
    10 + 5 + 1 = 16
    5 + 5 + 5 = 15
    5 + 5 + 1 = 11
    The total just reached 505 cents.
    There are a few more combinations left.
    5 + 1 + 1 = 7
    1 + 1 = 1 = 3

    Take the coins.
