Ticket-sale reveue for:
Thursday night: 200*40=8,000
Friday night: 240*50=12,000
Saturday afternoon: 220*40=8,800
Saturday night: 300*50=15,000

Maximum: 15,000
Minimum: 8,000

As a result, the difference between the maximum and the minimum ticket-sale revenue is: 15,000-8,000=7,000

The correct answer is D.

Solution



Given:
    • The data in the table shows the ticket sales from four performances of a certain play

To find:
    • The difference between the maximum and the minimum ticket-sale revenue from a single performance

Approach and Working:
We can calculate the revenues for each show as follows:
Ticket-sale Revenue = ticket price * number of tickets sold

Therefore,
    • Revenue on Thursday night = 40 * 200 = $8000
    • Revenue on Friday night = 50 * 240 = $12000
    • Revenue on Saturday afternoon = 40 * 220 = $8800
    • Revenue on Saturday night = 50 * 300 = $15000

Maximum revenue = $15000 and minimum revenue = $8000

Hence, the difference between the maximum and the minimum ticket-sale revenue from a single performance = ($15000 - $8000) = $7000

Hence, the correct answer is option D.

Answer: D

This question can be made simpler by considering that Thursday night's ticket price and number of tickets sold is the lowest of all four days, and vice versa for Saturday night.

So that means the minimum revenue has to be for Thursday night, i.e. $8,000, and highest for Saturday night, i.e. $15,000. Then calculations are as per everyone else'.

It's just good to be able to remove two potential calculations out of the equation early on, saves on time. :)

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

The wording "single performance" causes confusion here.

Solution :

$40 * 200 = 8000 <- Min
$50 * 240 = 12000
$40 * 220 = 8800
$50 * 300 = 15000 <- Max

15,000 - 8000 = 7,000

Hence D.
