Answer:
coefficient = 0
Explanation:
We have the formula to calculate the price elasticity of demand as following:
<em>Elasticity coefficient = % Change in quantity/ % Change in price</em>
As given:
+) The percentage change in price is: (120-150)/150= - 20%
+) The quantity bought remains unchanged - which means the percentage change in quantity demanded is 0%
=> <em>Elasticity coefficient = % Change in quantity/ % Change in price</em>
<em>= 0/-20 = 0</em>
<em />
<em>So the coefficient of price elasticity of demand in this example would be 0</em>
Answer:
A. 0.9x + 0.3y ≤ 10,000
Explanation:
Given
oil based plant
water based plant
The data can be represented in tabular form as:

Considering only A, we have the following constraints:


Since the company currently has 10000 of A.
The above constraint implies that, the mixture cannot exceed 10000.
So, we have:

<em>Hence, (A) is correct</em>
Answer:
A. Time series
B. Cross Sectional
C. Panel
D. Cross Sectional
Explanation:
(a) Quarterly data on the level of U.S. new housing construction from 2000 to 2018, Time series data, numerical
(b) Data on number of doctor visits in 2018 for a sample of 192 individuals. Cross sectional data, numerical
(c) Data on annual health expenditures for each U.S. state from 2000 to 2018. Panel Data, Numerical
(d) Data on usual mode of transportation used to commute to work for a sample of 151 individuals. Categorical
Answer:
1 EUR = 120 JPY
Explanation:
As the purchasing power parity theory, the exchange rate of currency 1 to currency 2 = Cost of good in currency 1
/ cost of same valued item in currency 2
In this case, a Lexus LS400 and a Mercedes C300 are considered to be of equivalent value, then the exchange rate between the yen and the euro
= price of Lexus in Tokyo/ price of Mercedes in Stuttgart
= 6,000,000 JPY/ 50,000 EUR
= 120 JPY/EUR
Answer
Miguel must set aside $62,745 annually
Explanation
N = Number of years till Miguel would retire = 43 years
FV = Future Value = $1,000,000
r = Interest rate = 10%
PMT = Annual payments (at the ending of the year) = ?? The question asks us to calculate this
We would use the future value ordinary annuity formula to calculate PMT
FV = PMT ![[\frac{(1+r )^{N} -1}{r} ]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B%281%2Br%20%29%5E%7BN%7D%20-1%7D%7Br%7D%20%5D)
1000000 = PMT ![[\frac{(1+0.10 )^{10} -1}{0.10} ]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B%281%2B0.10%20%29%5E%7B10%7D%20-1%7D%7B0.10%7D%20%5D)
PMT ≅ $62,745
Miguel must set aside $62,745 annually
