Question 53427: I have exactly 12 coins in my pocket worth exactly $1.00. I might have nickels, dimes, and/or quarters. What combinations of coins might I have? Find all the possibilities.
n=nickels, d=dimes, q=quarters. I set formula as n+d+q=12 and furthered it to .5n+.10d+.25q=$1.00. I wasn,t sure if I need a third formula or if I was right. I did a process of elimination with coins and came up with these combinations: #1 2q,0d,10n #2 1q,4d,7n #3 0q,8d,4n

You might have, by increasing number of quarters:
8 dimes, 4 nickels
4 dimes, 1 quarter and 7 nickels
2 quarters and 10 nickels
So it seems your solution is correct.
