Question 1063198
A jar filled with only nickels and quarters contains a total of 65 coins. The value of all the coins in the jar is $9.65. How many quarters are in the jar? 
--------------------------------------
Quantity:: n + q = 65 coins
Value:::: 5n+25q = 965 cents
--------------------------
Modify for elimination::
n + q = 65
n + 5q = 193
-------------------------
Subtract and solve for "q"::
4q = 128
----
q = 32 (# of quarters)
