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
