Total copies printed = 50000
Total copies sold = 50000 - 500 = 49500
Total copies sold at 1/2 price = 10% 0f 49500 = 4950
Total price sold at full price = 49500 - 4950 = 44550

Full price = $20
Half price = 20 * 1/2 = $10
Total revenue = (4950 * 10) + (44550 * 20)
= 49500 + 891000
=$940500

A publisher printed 50,000 copies of a book. All but 500 copies were sold
So, 50,000 - 500 = 49,500
So, 49,500 books we sold

Of the books sold, 10 percent were sold at half price, and the remaining copies were sold at the full price of $20.
10% of 49,500 = 4950
So, 4950 books sold for $10 apiece

49,500 - 4950 = 44,550
So, 44,550 books sold for $20 apiece

TOTAL revenue = (4950)($10) + (44,550)($20)
= 49,500 + 891,000
= 940,500
Answer: B

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
