Final answer:
To compute the revenue for each show, multiply the number of tickets sold by the ticket price. The variable costs for each show include the cast salaries and the program-printing cost.
Step-by-step explanation:
1. To compute the revenue for each show, you multiply the number of tickets sold by the ticket price. In this case, the average show sells 1,300 tickets at $60 per ticket, so the revenue per show is 1,300 x $60 = $78,000.
The variable costs for each show include the cast salaries and the program-printing cost. The cast of each show consists of 65 members, each earning a net average of $340 per show. So, the total cast expenses per show are 65 x $340 = $22,100. The program-printing cost per guest is $8, so the total program-printing cost per show would vary depending on the number of guests.
