Sean has $2.05 in nickels and quarters. If he has 25 coins all together, then how many of each coin does he have?
------------
If they were all nickels, he'd have $1.25 (25*5)
Each nickel that is replaced by a quarter adds 20 cents.
80 cents has been added (205 - 125)
80/20 = 4 replacements
--> 4 quarters & 21 nickels
