You can put this solution on YOUR website! You find a total 11 coins totaling $1.95 in the bottom of your Mom's purse. There are only quarters and nickels. How many of each do you have?
============
The hard way:
Q + N = 11
25Q + 5N = 195
===============
Or,
If it were 11 nickels it would be 55 cents.
Each Q that replaces a nickel adds 20 cents.
--
195 - 55 = 140
140/20 = 7 quarters.
---> 4 nickels
