Question

hi in need of help, pls solve this for me
TR (R) = 1980Q-9Q^2
TC (C) = 200 +6Q^2 where Q is the quantity sold

1.Marginal Revenue Equation.
2.The Marginal Cost Equation , the quantity that will maximize revenue.
3. the quantity that will minimize cost, the profit equation.
4.the quantity which will maximize the profit.
5.the maximum profit.

Please please answer the above it will be much appreciated, Thankx!!

Answer 1

TR mean revenue , and C mean Cost?

Answer 2

1) Take derivative of R to get marginal revenue
2) Take Derivative of D of get Marginal cost equation

Answer 3

yes TR mean revenue and C means Cost . is it possible for you to answer the cost question please...

Answer 4

Take derivative of cost equation
TC (C) = 200 +6Q^2
marginal cost
12 Q

Answer 5

so taking that answer i can find the quantity that will minimize the cost yah..?

Answer 6

I am not sure about minimizing and maximizing in this context

Answer 7

Profit= Revenue - Cost

Answer 8

oki cool thankx alot :-)

Answer 9

Profit(Q)=(1980Q-9Q^2)-(200 +6Q^2 )

Answer 10

yah that part i understand its the part where i have to find the max and min of MR and MC..

Answer 11

bit confused there..

Answer 12

thankx again for the help....
