Question 799889: You've just opened your piggy bank to discover 55 coins totaling $10.00. If there are more nickles than pennies, more dimes than nickles and more quarters than dimes, how many of each coin do you have?

You can put this solution on YOUR website! In order of the most to the least, you have:
Q
D
N
P
You can have 5 pennies or 10 pennies
Suppose
Q = ?
D = 1
N = 1
P = 5
-------
Now I need to put the amounts in descending order
Q = ?
D = 7
N = 6
P = 5
D + N + P = 18 and that amount is $1.05
Add 2 more dimes, and I get $1.25, or 5 quarters
Now I have:
Q = 1000/25 - 5 = 35
D = 9
N = 6
P = 5
--------
Total coins is 55, and
P*1 = 5
N*5 = 30
D*10 = 90
Q*35 = 875
-----------
1000 cents total or $10.00
Hope this makes sense
