<PRE><B>Question 255848</B>
Call book price x and magazine price y
Then 4x + 3y = 145     ..............A
and  2x + 5y = 125     ..............B 
     4x +10y = 250     ..............C = 2B
          7y = 105     ..............D = C - A
           7 = 15

Sub in A  4x + 45 = 145
            x = 25

Check in B
2 x 25 + 5 x 15 = 50 + 75 = 125
So books are 25cents and magazines are 15cents</PRE>
