There are 9 different solutions to this puzzle. It is tied for the most number of solutions for a specified number of coins (the other is making 15 coins equal a dollar). The first solution uses 0 pennies, just nickels and dimes, and should be pretty easy to find if you remember that 20 nickels equals a dollar. Two solutions use 5 pennies, either with just nickels and dimes, or with 1 quarter. There are four solutions that use 10 pennies (if you allow half dollars). And two solutions that use 15 pennies (one that uses half dollars). This kind of puzzle is always more fun if you try to systematically find ALL the answers instead of just the first one you come across. Have fun!

How can you use 24 coins to make 1 dollar?
19 nickels and 5 pennies.
Can you make 25 cents with 19 coins?
not with todays coins.... when they had 2 cent pieces etc yes
How do you make four twos equal 19?
4!-(4/4+4)=19
11 plus (19 plus 6)equal (11 plus 19) plus 6?
11 + (19 + 6) = 36(11 + 19) + 6 = 36So they are both equal. The brackets make no difference in this case.
What is the largest possible value of coins is it possible to have without having any coins which will add to 4 dollars coins are 5c 10c 20c 50c 1 dollar 2 dollar?
Tentatively I will say $4.35, with for instance: 19 x 20c 1 x 50c 1 x 5c It's possible that a rigorous method exists, but this is just a fudged guess. Any advances on it?
