Answer:
39 weeks
Explanation:
initial investment = $5 million
Your goal is to a better person and get rich by doubling your development costs. You want to earn $10 million in profits, so you will need to sell a lot of seats.
8 shows per week x 100 weeks = 800 shows
revenue per ticket = $50 + $1.50 = $51.50
tickets sold per show = 800 x 80% = 640
total revenue per show = 640 x $51.50 = $32,960
variable cost per show (assuming 7 nights per week) = $7,000 / 8 = $875
contribution margin per show = $32,960 - $875 = $32,085
number of shows needed to earn $10 million in profits = $10,000,000 / $32,085 = 311.67 shows
number of weeks = 311.67 / 8 = 38.96 ≈ 39 weeks
