Here's the task out of the exam last year:
As a pricing manager at X you have estimated the following price demand function for TV 2.0 (for a price per month in USD):
x(p) = 2'000'000 - 40'000 p
--> What is the price elasticity at a price of 20 CHF? What would you recommend to do?
I know now how to solve normal elasticity tasks where P∆ is noted, but its not visible for me here - can someone help me out?
Thanks a quadrillion times :)
