OK HERES THE QUESTION..

I bought two books for a total cost of $40. If the first book's price were raised 5% and the second's lowered 5%, the prices would be equal. What was the original price, in dollars, of the cheaper book?

let x = price of cheaper book
x+y = 40 and x(1.05) = y(0.95)
so x = $19.00

let the first book is $x and other one is $y

so x+y=40 ---------> 1

x+x/20=y-y/20
so 21x=19y

so x=$19
and
y=$21
