In your piggy bank, you have $6.80, which is a combination of 39 coins(quarters and dimes only).
Is it possible to have 39 coins of quarters and dimes only?
--------
Equations::
Quantity of coins: d + q = 39 coins
Value of the coins 10d + 25q = 680 cents
--------------------------
Modify::
10d + 10q = 10*39
10d + 25q = 680
------
Subtract and solve for "q":
15q = 290
q = 19 1/3 (not a realistic number of quarters)
----
Ans: It is not possible.
