they have
5 * 25 + 3 * 10 + 5 * 5 = 125+30+25 = 180 cents
So each gets 90 cents
greg has
2 * 25 + 1 * 10 + 3 * 5 = 75 cents
stan has
3 * 25 + 2 *10 + 2 * 5 = 105 cents
stan must give greg 15 cents, a dime and a nickel
5 * 25 + 3 * 10 + 5 * 5 = 125+30+25 = 180 cents
So each gets 90 cents
greg has
2 * 25 + 1 * 10 + 3 * 5 = 75 cents
