Answer:
0.60
Explanation:
The midpoint formula is used to calculate elasticity by using average percentage in both price and quantity.
The formula is given below:
Percentage change in quantity =<u> (Q2 -Q1) </u> x 100
(Q2 + Q1) / 2
Percentage change in price = <u> (P2 -P1) </u> x 100
(P2 + P1) / 2
Elasticity =<u> Percentage change in price__</u>
Percentage change in quantity
Inserting the data:
Percentage change in quantity =<u> (30 -20) </u> x 100 = <u>10</u> x 100 = 40%
(30 + 20) /2 25
Percentage change in price = <u>($20 - $10)</u> x 100 = <u>10</u> x 100 = 66.6%
($20 + $10) /2 15
Elasticity of supply = <u>40%</u>
66.6%
= 0.60
Answer:
-0.10
Explanation:
To calculate this, we us the formula for calculating elasticity of demand (E) relevant for the demand equation as follow:
E = (P / Q) * (dQ / dP) .............................. (1)
Where,
Q = 30
P = 90
E = -0.3
dQ / dP = b = ?
We then substitute all the value into equation (1) and have:
-0.3 = (90 / 30) * b
-0.3 = 3 * b
b = -0.3 /3
b = -0.10
Therefore, appropriate value for the price coefficient (b) in a linear demand function Q is -0.10.
NB:
Although this not part of the question, but note that how the linear demand function will look can be obtained by first solving for the constant term (a) as follows:
Q = a - 0.10P
Substituting for Q and P, we can solve for a as follows:
30 = a – (0.1 * 90)
30 = a – 9
a = 30 + 9 = 39
Therefore, the linear demand equation can be stated as follows:
Q = 39 – 0.1P
The answer is a.True
The cost of the fixed asset is already excluded from the net income. In this case, the rate of return can be computed by the total net income divided by the cost of the fixed asset. So that would be $200,000/$400,000. The rate of return would be 50%
Answer:
15.4%
Explanation:
Calculation to determine your best guess for the rate of return on the stock
The revised estimate on the rate of return on
the stock would be:
Before
14% = α +[4%*1] + [6%*0.4]
α = 14% - 6.4%
α = 7.6%
With the changes:
7.6% + [5%*1] + [7%*0.4]
= 7.6% + 5% + 2.8%
= 15.4%
Therefore your best guess for the rate of return on the stock will be 15.4%
