A company produces and sells a consumer product and is able to control the demand for the product by varying the selling price. The approximate relationship between price and demand is 50 units.

p = 38 + (2,700 / D) - (5,000 / D2)

Marginal (variable) cost (MC) = 40

(a) Profit is maximized by equality of Marginal revenue (MR) and MC.

Total revenue (TR) = p x D = 38D + 2,700 - (5,000 / D)

MR = dTR / dD = 38 + (5,000 / D2)

Equating MR with MC,

38 + (5,000 / D2) = 40

5,000 / D2 = 2

D2 = 2,500

Taking positive square root on each side,

D = 50

(b) When D = 50, from demand function we get

p = 38 + (2,700 / 50) - (5,000 / 2,500) = 38 + 54 - 2 = $90 (Profit-maximizing price)

Profit (\pi) ($) = Total Revenue - Total Costs = TR - (Fixed cost + Total variable cost) = (p x D) - (1,000 + 40D)

= 38D + 2,700 - (5,000 / D) - 1,000 - 40D

= 1,700 - 2D - (5,000 / D)

Profit is maximized when d\pi/dD = 0 and d2\pi/dD2 < 0.

First order condition: d\pi/dD = - 2 + (5,000 / D2)

Second order condition: d2\pi/dD2 = d/dD(d\pi/dD) = - 2 x (5,000 / D3) = - 10,000 / D3

Since D > 0, (- 10,000 / D3) < 0, which proves that profit is maximized when company produces = 50 units.

you invest $1300 in an account at interest rate r, compounded continuously. Find the time required for the amount to double and
miskamm [114]

Answer:

  • 1. <em>For the amount to double</em>: <u>9.37 years</u>
  • 2. <em>For the amount to triple</em>: <u>14.85 years</u>

Explanation:

The equation for continuosly compounded interest is:

  • F=P\times e^{rt}

Where:

  • P is the amount that you invest today: $1,300
  • F is the value after t years: the double or triple of $1,300
  • r is the annual interest rate: 0.074

<u>1. For the amount to double:</u>

Substitute the values and solve for t:

             2\times \$1,300=\$1,300\times e^{0.074t}\\ \\ 0.074t=\ln 2\\ \\ t=\ln 2/0.074=9.37years

<u>2. For the amount to triple:</u>

<u />

            3\times \$1,300=\$1,300\times e^{0.074t}\\ \\ 0.074t=\ln 3\\ \\ t=\ln 3/0.074=14.85years

A difference between explicit and implicit costs is that a) explicit costs must be greater than implicit costs. b) explicit cost
Andrej [43]

Answer:

Implicit costs do not require a direct monetary outlay by the firm, whereas explicit costs do.

Explanation:

Rent, salary, and other operating expenses are considered explicit costs. They are all recorded within a firm's financial statements, meaning they are present and clearly shown or reported as a separate cost. The main difference between the two types of costs is that implicit costs are opportunity costs, meaning that it is present but it is not initially shown or reported as a separate cost, while explicit costs are expenses paid with a company's own tangible assets. In other words, explicit costs are always shown, implicit costs are not, at least initially, exactly like the meaning words suggest.

<h3>What does the term "investment decision" mean?</h3>

The choice and acquisition of the long-term and short-term assets in which funds will be invested by the organization are referred to as investment decisions.

<h3>What is a timing option for investments?</h3>

The investment-timing option, which is the choice to delay rather than immediately adopt or reject a capital budgeting project, can dramatically boost a project's value when interest rates are unpredictable.
