OK here's 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?

I need the aNswer soon! I love you who answers this. Thank you SO much!

Get Real, this forum isn't for doing your homework. Ask for hints not answers. >:(

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
