You can put this solution on YOUR website! sue has $1.95 in dimes and nickels. If she has 9 more dimes as nickels, how many of each coins does she have?
========================
Put the "9 more dimes" aside --> pairs of dimes and nickels worth $1.05.
They're 15 cents each
105/15 = 7 pairs
--> 7 nickels & 16 dimes
============================
The hard way:
d = n + 9
10d + 5n = 195
Solve for d and n
