If the demand curve for a particular commodity is p = −0.09x + 51 and the total cost function C(x) = 1.32x2 + 11.7x+ 101.4,where x is the level of production: Find (a) The revenue R(x) and profit Π(x). How much will have been spent on production by the end of the third hour? When will the total manufacturing cost reach $11,000?
a. Revenue R(x)= P*x= -0.09x^2+51x
Profit π(x)= Revenue - Cost=R(x)- C(x)
π(x)= -0.09x^2+51x-1.32x^2- 11.7x-101.4
π(x)= -1.41x^2+39.3x-101.4
C(x)= 11000= 1.32x^2+11.7x+101.4
0= 1.32x^2+11.7x-10898.6
Solving for positive value of x,
we get x=86.5
When production =86.5, manufacturing cost reach $11000

A monopolist faces the following demand curve: Q = 80 – 0.2P Where Q is the weekly production and P is the price, measured in $/unit. The firm’s cost function is given by C = 100 + 20Q2 . Assuming the firm maximizes profits, Find the equation describing the marginal revenue (MR) curve. What is the level of production (Q), price (P), and total profit (π) per week? If the government decides to levy a per-unit tax of 50 $/unit...
A commodity has a demand function modeled by p = 280 − 0.4x, and a total cost function modeled by C = 80x + 120, where x is the number of units. (a) What price yields a maximum profit? (b) Find the average cost per unit when x = 50 and x = 650. (c) Determine when the demand is elastic, inelastic, and of unit elasticity. (d) Use differentials to approximate the change in revenue as sales increase from 210...
You are a monopolist in a market with an inverse demand curve of: P=10-Q. Your marginal revenue is: MR(Q)=10-2Q. Your cost function is: C(Q)=2Q, and your marginal cost of production is: MC(Q)=2. a) Solve for your profit- maximizing level of output, Q*, and the market price, P*. b) How much profit do you earn?
A firm faces the following average revenue (demand) curve: P = 120 – 0.02Q where Q is weekly production and P is price, measured in cents per unit. The firm's cost function is given by TC = 60Q + 25,000. Assume that the firm maximizes profits. Calculate the level of production, price, and total profit per week.
Suppose that poutine ice cream is a hot commodity with the inverse market demand function ?(?) = 50 − ?/100 where ? denotes quarts per week. There is only one confectioner with the secret recipe. Despite their tireless efforts, other confectioners cannot replicate this tasty treat. A. What kind of market is this? B. What is the confectioner’s total revenue function? C. From the total revenue function, we know that marginal revenue is ??(?) = 50 − ?/50 . Moreover,...
A firm faces the following average revenue (demand) curve: P= 135 -0.020 where Q is weekly production and P is price, measured in cents per unit.
