Question 850042
The Book Nook makes four times as much revenue on paperback books as on hardcover books. If last month's sales totaled $124,300, how much was sold of each type book? 
-------
Let value of hardcover books = x
Then value of paperback books = 4x
-----
Equation:
x + 4x = 124,300
5x = 124300
x = 24860
4x = 99440
