.
Roger has $2.60 in quarters and dimes. He has 14 coins altogether. 
How many coins of each kind does he have?
~~~~~~~~~~~~~~~


<pre>
Q quarters;  (14-Q) dimes.


Write the total money equation

    25Q + 10*(14-Q) = 260   cents.


Simplify and find Q

    25Q + 140 - 10Q = 260

    25Q - 10Q = 260 - 140

        15Q   =    120

          Q   =    120/15 = 8.


<U>ANSWER</U>.  8 quarters and (14-8) = 6 dimes.

Solved.
