    So its a penny and a half dollar that will give you $0.51 so you can do this

    starting with your 51 penniesyou can get rid of every 5 pennies and replace them with a nickel so say you get rid of 10 pennies you would have 2 nickels

    so 51/5 = 10.2

    or 10 nickels

    so that is ten combos right there along side 51 pennies

    so no you do the dimes witch for every 10 pennies you get rid of is = to 1 dime so 51/10=5.1 or 5 dimes so that gives you 5 more combos

    so now its 1 penny combo with 10 nickel combos with 5 dime combos

    now for quarters for every 25 pennies you get rid of is = to 1 quarter so

    51/25=2.04 or just 2 and with half dollars (they do make thoses) it is for every 50 pennies you get rid of is = to one half dollar (which is 50 cents) so 51/50 = 1.02 or 1 so it is

    1 penny combo + 10 nickels combos + 5 dime combos + 2 quarter combos + 1 half dollar combo =

    1+10+5+2+1=19 different sums of money
