Question 63925:  Kindly Help !!
 
USA TWO (UT) processes and sells Tea and coffee products. UT’s revenue function is of the Form R = ax + by ( $ 000 ) , where X and Y are tons of Tea and Coffee products sold . John, in an effort to establish the specific form of the revenue function obtained the following data.
 
John has also established that UT’s total cost function is specifically:
 
C = 10x^2 + 20 y^2 + 10xy 
 
Determine the tones of each product that should be processed and sold to maximize profit and the maximum profit

You can  put this solution on YOUR website! USA TWO (UT) processes and sells Tea and coffee products.

Determine the tones of each product that should be processed and sold to maximize profit and the maximum profit 
 
-------------- 
Profit = Revenue - Cost 
Profit = (ax+by)-(10x^2+20y^2+10xy) 
Comment:  To find the maximum of the profit you could take the derivative 
of this Profit equation; then find its zeroes.  But the derivative expression 
will have two variables and you have not been provided additional information 
which could lead to a conclusive answer to the question.
