For the following demand equation compute the elasticity of demand and determine whether the demand is elastic, unitary, or inel
Andreas93 [3]

Answer:

Note: While answering this question, there is a confusion as to whether the correct demand equation is p= 157 − x2 as it appears in the question, or p= 157 − x^2 which is suspected to be the correct equation. Whichever the case may be, answers are provided for the two equations. Just confirm from the original question or your teacher which one is correct and pick the relevant answer out of the two following answers:

1. If p= 157 − x2 is the correct equation:

Elasticity of demand = - 0.15

Since -0.15 in absolute term |-0.15| is less than 1, the demand is inelastic.

2. If p= 157 − x^2 is the correct equation:

Elasticity of demand = - 0.28

Since -0.28 in absolute term |-0.28| is less than 1, the demand is also inelastic.

Explanation:

Elasticity of demand is the degree of responsive of quantity demanded of a good to change in its price.

For this question, elasticity of demand can be computed using the formula for calculating the elasticity of demand as follows:

1. If p= 157 − x2 is the correct equation

E = Elasticity of demand = (p / x) * (dx / dp) ............................... (1)

From the question, we have:

p = 157 − x2.

Therefore, we solve for as follows:

x2 = 157 - p

x = (157 - P) / 2

x = 78.5 - 0.5p ....................................................... (2)

Differentiating equation (2) with respect to p, we have:

dx/dp = -0.5

Substituting values for dx/dp and x into equation (1), we have:

E = [p / (78.5 - 0.5p)] * (-0.5)

Since p = 20, we have:

E = [20 / (78.5 - (0.5 * 20))] * (-0.5)

E = [20 / (78.5 - 10)] * (-0.5)

E = − 0.15

Since -0.15 in absolute term |-0.15| is less than 1, the demand is inelastic.

2. If p = 157 − x^2 is the correct equation

E = (p / x) * (dx / dp) ............................................ (1)

From the question, we have:

p = 157 − x^2.

Therefore, we solve for as follows:

x = 157^(1/2) – p^(1/2)

x = 157^0.5 – p^0.5 ........................................... (2)

Differentiating equation (2) with respect to p, we have:

dx/dp = -0.5p^(-0.5) = -0.5/p^0.5

Substituting values for dx/dp and x into equation (1), we have:

E = (p / x) * (dx / dp)

E = [p /  (157^0.5 – p^0.5)] * [ -0.5/p^0.5]

Since p = 20, we have:

E = [20 /  (157^0.5 – 20^0.5)] * [–0.5/20^0.5]

E = - 0.28

Since -0.28 in absolute term |-0.28| is less than 1, the demand is inelastic.

What might you send to people who buy a house with no water?
g100num [7]
It is a well-known fact that water is a basic need of a human being in order to survived. Generally, a person is known to survive for only 3 days without water. Thus, the best thing that I would send to a person who bought a house with no water is any amount of water which will allow them to survive until they procure their own supply.

For 2019, Skresso Co. reported $1.82 of earnings per share of common stock. During 2020, the firm had a 4% common stock dividend
mart [117]

Answer:

$1.75

Explanation:

Earnings per share to be reported = Earnings per share of commo stock * (1 - 4%)

Earnings per share to be reported = $1.82 * 96%

Earnings per share to be reported = $1.7472

Earnings per share to be reported = $1.75

So, the 2019 earnings per share to be reported in the annual report for 2020 are $1.75.

If an economy is producing at a point on its production possibilities frontier, it is: a.efficient in production and allocation.
irinina [24]

Answer:

d.efficient in production but not necessarily in allocation.

Explanation:

The production possibility curve portrays the cost of society's choice between two different goods. An economy that operates at the frontier has the highest standard of living it can achieve, as it is producing as much as it can using the same resources. If the amount produced is inside the curve, then all of the resources are not being used.

- all points on the curve are points of maximum productive efficiency

- However, an economy may achieve productive efficiency without necessarily being allocatively efficient. Market failure (such as imperfect competition or externalities) and some institutions of social decision-making (such as government and tradition) may lead to the wrong combination of goods being produced (hence the wrong mix of resources being allocated between producing the two goods) compared to what consumers would prefer, given what is feasible on the PPF.
