Question 1196792
.
<pre>

x = number of 50-cent pieces

(30-x) = the number of quarters.


Write the total money equation

    50x + 25*(30-x) = 950  cents  (the total change)


Simplify and find x

    50x + 750 - 25x = 950

       25x          = 950 - 750

       25x          =    200

         x          =    200/25 = 8.
