Answer:
20 years (scenario A) and 16 years (scenario B)
Explanation:
The real GDP will double in "n" number of years, with "n" estimated by interpolation using the formula below.

In the solutions below, we assumed current GDP to be 1, and as a result, the GDP will double to 2.
Scenario A

When you substitute 20 for "n" in the left hand side (LHS) of the equation, you will arrive at 1.99 which is approximately equal to 2. Any number below 20 will result in a number less than 2.
Thus, with an average annual real GDP growth rate of 3.5%, real GDP will double in about 20 years.
Scenario B

When you substitute 16 for "n" in the left hand side (LHS) of the equation, you will arrive at 2.02 which is approximately equal to 2. Any number below 16 will result in a number less than 2.
Thus, with an average annual real GDP growth rate of 4.5%, real GDP will double in about 16 years.
Answer:
$1,375
Explanation:
Given the information above, the Ending inventory = Units available - Units sold
Units available = 10 + 25 + 30 + 70 = 80
Units sold = 60
Ending inventory = 80 - 60
Ending inventory = 20
Cost of ending inventory under FIFO
= (15 × $70) + (20 - 15) × $65
= $1,050 + $325
= $1,375
Therefore, the ending inventory cost using FIFO is $1,375
Macroeconomics is important because it allows the public to understand the economy as a whole, fiscal policy and global economic policy.
Answer: B. D) are not materially different from ethical principles in general.
Explanation:
Ethical Principles are Ethical Principles. It doesn't really matter what context they are being applied to for they are a standard thing with reference of course, to the society the business is based in. For this reason Business Ethics are not materially different from general ethics.
Business Ethics are usually a reflection of the norms and cultures of the society they are based in. Think of it like this, if a company is based in a certain place and adheres to principles that are different from what is considered ethical in that society, do you think that company will be very profitable? I think not. Business Ethics are therefore based on General ethics with an immaterial difference.
