Let P stand for the amount of money made on selling paperback books.
Let H stand for the amount of money made on selling hardcover books.
Then: P + H = 124,300
But, since they make four times on paperback books as on hardcover books: P = 4H
4H + H = 124,300
5H = 124,300
H = 24,860
P = 4H = 4(24,860) = 99,440
