Answer:
The correct answer is option a.
Explanation:
The initial price of movie rentals is $3.25.
The initial quantity is 100.
The price falls to $3.
This causes demand to rise to 120.
The price elasticity of demand a ratio of change in quantity demanded to change in price level.
The elasticity is calculated at -2.25, through the process given in images.
The price elasticity of demand here is greater than 1 which means it is elastic.
So, option a is the correct answer.
Answer:
ii. Her accounting profit was $150,000
iii. Her economic profit was $50,000
Explanation:
The computation is shown below:
For accounting profit, it is
= Total revenues - total expenses i.e explicit cost
= $250,000 - $100,000
= $150,000
And, for economic profit
= Total revenues - total cost i.e explicit and implicit cost
= $250,000 - $100,000 - $100,000
= $50,000
Hence, the second and third options are correct
Answer:
Final Value= $4,216,869
Explanation:
Giving the following information:
You have decided that one year from today you will begin depositing 10 percent of your annual salary in an account that will earn 9.2 percent per year. Your salary will increase at 3 percent per year throughout your career. Your salary is $52,000
Your retirement is in 40 years.
We need to use the following formula:
FV= {A*[(1+i)^n-1]}/i
A=annual payment= 5,200
i= 9.2% interest + 3% year increase= 12.2%
n=40
FV= {5,200*[(1.122^40)-1]}/0.122
FV= $4,216,869
Answer:
The incorrect statement is number (2): Data marts typically have broader focus than data warehouses.
Explanation:
Data marts are data structures built on a database. In this structure, consolidated data is stored that will be used as a feed for an analysis tool. Data marts are specialized in storing data of a specific area of an organization. A group of datamarts is called Datawarehouse.
