‘Up in the Air’ by Walter Kirn, and ‘Revolutionary Road’ by Richard Yates.

I bought the February 2010 edition of K-Zone Philippines, and the movie-tie-in editions of ‘Revolutionary Road’ and ‘Up in the Air’. ‘Revolutionary Road’ is written by Richard Yates, and published on December 31 1961, and ‘Up in the Air’ written by Walter Kirn, and published in 2001.

The original prices of K-Zone Philippines issues are 95 pesos. Due to that they had a booth in the recent-concluded 31st Manila International Book Fair, all issues being sold by Summit Media costs 50 pesos.

The novels, ‘Revolutionary Road’ by Richard Yates, and ‘Up in the Air’ written by Walter Kirn, originally costs 315 pesos. Due to that National Book Store had a booth in the the recent-concluded 31st Manila International Book Fair, all books being sold by NBS are under 20% off.

If you don’t understand, I will explain this way. If a customer buys a book, he/she will avail the 20% off, if he/she going to buy the book being sold by NBS. Like what happened to me yesterday. I bought the novels, ‘Revolutionary Road’ by Richard Yates, and ‘Up in the Air’ written by Walter Kirn, these two/2 books costs 315 pesos. Because of the 20% off being sold by NBS, the two/2 books costs 252 pesos.

The original price of the novels is 315 pesos, time by 2/two, equals 630 pesos. 315 * 2 = 630.

With the 20% off:
315 times 2 equals 630 * .20 = 126 and then 630 – 126 = 504
