Hi, looking for help regarding price elasticity. What would be the best method to maximize revenue for a given demand curve (Q = 6.504 - 2.565P + 0.143T) where T is constant at 80 (shifter)? I used trial and error to plug in various values to get $3.50 that would give an ep of -1, but is there a more appropriate function to use, like setting ep to -1 and solving for price? Not sure if more info is needed to solve this. I put together a demand curve, keeping 80 for T as a constant and solving Q using 0.50 increments of price. Thank you.
