¶ … Production Cost Per Edition Is
TC (Q) =70+0.10Q+0.001Q2 />
M ? = 0.90Q - (70+0.10Q+0.001Q2 )
Functions
(i) Total Revenue Function
Total Revenue is normally calculated by multiplying the price of the product with the quantity sold.
TR (Q) =P (Q) x Q. where Q. is the quantity of output sold, and P (Q) is the inverse demand function of the price.
Price per unit is
Simplified function 0.90Q2
Profit Function
The profit is calculated by subtracting the production cost from the total revenue
(Q) = TR (Q) - TC (Q)
Production cost =70+0.10Q+0.001Q2
P (Q) x Q -- (70+0.10Q+0.001Q2) where P. Or ? is the price per Unit
PQ2-70+0.10Q+0.001Q2
Price per copy is
Q2 -70+0.10Q+0.001Q2
Profit Function = 0.9010 Q2 +0.10Q -70
Marginal Revenue Function
The marginal revenue is the extra revenue that comes from selling 1 additional unit. The change in revenue with respect to a change in quantity must be computed first.
MR (Q)= d (TR) Where'd represent derivative dQ
Total Revenue function = 0.90Q2
MR (Q)= d (TR) =d (0.90Q2)
dQ d (Q)
Marginal cost Function
The marginal unit is the last unit. Therefore, marginal cost is the cost of the last unit, or what it costs to produce one more unit. The change in costs from a previous level divided by the change in quantity from the previous level is represented by MC = Change in TC / Change in Q
MC (Q)= d (TC)
d (Q)
The function is =MC (Q)=d (70+0.10Q+0.001Q2)
d (Q)
Marginal profit Function
M ? = R ' (Q) - C ' (Q)
Marginal revenue is d (0.90Q2) - d (70+0.10Q+0.001Q2)
d (Q) d (Q)
M ? = 0.90Q2 - (70+0.10Q+0.001Q2 )

Q
Average cost function
Average cost is total revenue divided by the number of quantity
MC= 0.90Q2
Q
Manipulate the total revenue, profit, marginal revenue, marginal cost, marginal profit and average cost given that Q=500
Total revenue
TR (Q) =P (Q) x Q= 0.90Q2
0.90 x 5002 =0.90 x 250000
TR=225000
(i) Profit
Profit function is 0.9010 Q2 +0.10Q -70
Q=500
(0.9010 x 5002 ) + (0.10 x 500) -- 70
225250 + 50-70
P =225230
(ii) Marginal Revenue
Marginal revenue function is MR (Q) = d (TR) =d (0.90Q2)
dQ d (Q)
Q=500
=d (0.90Q2)
d (Q)
500 = 0.90 x 250000 = 450
MR = 450
(iii) Marginal cost
The MC function is d (70+0.10Q+0.001Q2)
d (Q)
Q=500
d (70+0.10Q+0.001Q2)
d (Q) = 70+0.10Q+0.001Q2
Q
70+ (0.10 x 500) + (0.001 x 5002 ) = 70+50 +250
MC = 370
(iv) Marginal profit
The marginal profit function is
M ? = 0.90Q - (70+0.10Q+0.001Q2)
Q
Q= 500
Therefore, M ? is (0.90 x 500) - 70+ (0.10 x 500) + (0.001 x 5002 )
=450-70 + 50 +250
M ? = 450-370/500 = 449.26
(v) The average cost
Average cost function is MC= 0.90Q2
Q
0.90 x 5002 = 225000/500 = 450
(b) Profit maximization
Since marginal cost of $370 is less than marginal revenue of $450, the newspaper sales should be increased to optimize profit until marginal cost equals marginal revenue.

Even the lowest-level managers and employees are empowered to make decisions and have that valued democratic voice. ADVANTAGES: An advantage of this form of measurement is that it tends to be more encompassing, since it accounts for all uses of capital. It is susceptible to manipulation by managers with a short-term focus, or by manipulating the hurdle rate used to evaluate divisions. The frequently occurring problem, in concern to a lack
Calculate the Profit-Maximizing Price Economics To calculate the profit-maximizing price and output level of the firm, the paper starts from price $10 to $200. The paper uses the Excel software to calculate the quantity, revenue, marginal revenue, variable costs, total costs and marginal costs. The fixed costs of the firm are $120, which does not change no matter the level of quantity produced. However, the variable costs decline with the increase in the
