<PRE><B>Question 1054748</B>
 I have 12 coins that total the value of $2.25. If there are only quarters and dimes, how many of each kind are there.
----------
d + q = 12 coins
10d + 25q = 225 cents
----------------------------
2d + 2q = 24
2d + 5q = 45
----------------------
Subtract and solve for &quot;q&quot;::
3q = 21
q = 7 (# of quarters)
-------------------
d = 12-q = 12-7 = 5 (# of dimes)
----------------
Cheers,
Stan H.
