Pen was $9, book was $3.
You make an algebraic equation to find the answer. By reading the problem, you could say that the book was x and the pen was 3x dollars. So, x + 3x = 12, or 4x = 12, so x = 3 (which was the price of the book, remember), and the pen is 3x or 3 x 3, or $9.

Here's how to do it, so you don't need to ask other people to do your homework anymore:
Price of book + price of book times 3 = Total
therefore
price of book times 4 = total
therefore
price of book times 4 = 12
one fourth of twelve is 3
price of book = 3
price of pen = 9

check!

x+3x=12
4x=12
/4 /4
x=3
book=x
x=3
pen=3x
3(3)=9
