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

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.

A. \$4,000

B. \$5,100

C. \$6,200

D. \$7,000

E. \$9,600

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.

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.

Solution:

Minimum value should be b/w Thu and Sat afternoon with 40\$/ticket whereas maximum price between Friday and Sat night with 50\$/ticket
(as 220 corresponding to 40\$,the bigger value b/w 200 and 220 is less than both 300 and 240 corresponding to 50\$)

Between Thu and Sat the minimum value = 40*200 = 8000\$

Between Fri and Sat night the maximum value =50*300= 15000\$

Difference = 15000\$-8000\$

=7000\$ (option d)

Approach 1: Calculate fully.

Approach 2: Abhishek's approach of not using zeros, but calculating all four

Approach 3: Consider that all tickets were for 50. So, number of tickets will go down for two of the columns. We can now quickly see min and max, and without using zeroes, we have the answer using subtraction.
