Hi All,

We're told that the table shows a summary of the ticket sales from four performances of a certain play. We're asked for the DIFFERENCE between the MAXIMUM and the MINIMUM ticket-sale revenue from a single performance. This question comes down to a little analysis of the given data and a bit of Arithmetic.

Since there are only 4 'entries' in the table, it wouldn't be too difficult to calculate the revenue from each of the 4 shows. However, not all of that work is necessary.

The MAXIMUM revenue is clearly from Saturday Night (most expensive price and largest number of tickets).... ($50)(300) = $15,000 in revenue.
The MINIMUM revenue is clearly from Thursday Night (least expensive price and smallest number of tickets).... ($40)(200) = $8,000 in revenue.
Thus, the difference is $15,000 - $8,000 = $7,000

Final Answer: D

The maximum revenue was 50 x 300 = $15,000.

The minimum revenue was 40 x 200 = $8,000.

So the difference is 15,000 - 8,000 = $7,000.

Answer: D

"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 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 gives you a deep understanding of the concept you need to know while teaching you how to think."
