Question 1161198
.
The revenue from selling 'q' items is R(q)= 325-q^2, and the total cost is C(q)=50+14q. 
Write a function that gives the total profit earned, and find the quantity which maximizes the profit. 

Profit pi(q)=?
Quantity maximizing profit q=? 
~~~~~~~~~~~~~~~~~~~~~



The given "revenue function"  R(q) = 325 - q^2  of the number "q" of sold items is monotonically DECREASING function,
according to the posted formula.



But it NEVER may happen that the revenue function be a DECREASING function of the number of sold items.



It is for the first time in my life I see such an absurdist statement.


Imagine: you sell something, and the amount of money in your pocket is decreasing . . .  



It may happen only if the seller <U>pays exra</U> from his pocket to a buyer for every "sold" item . . . 



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Who created this nonsense ?



O my god, it goes under the section "Finance" . . . 


It looks like the author is studying Finance . . . 


Good luck then . . . 



Thank you for making me laugh . . .
