Question 233465
divide 2.05 (2 dollars and a nickel) into 12.25.
12.25/2.05=5.9...
So, there can't be more than 5 nickels and since 12.25 ends in a five there can only be 1, 3 or 5 nickels.
5 seems the most likely.
5=.25
5*$2=10
12.25-20*.1=2
=12.25 with 10 dollars, 20 dimes and 5 nickels.
There is probably a more elegant way to solve this but I don't know what it is.
