Given that:

Inflation rate = 2%

The expected value of an investment = 82,500

Now,

nominal terminal value of the investment at the end of year 4.

Thus,

The nominal terminal value rate at the end of year four is given as follows:

= 82, 500 * (1 +2%) ^4

According to the Core Reading, which of the following is NOT a threat presented by rising income inequality? Select one: a. High
Vilka [71]

Answer:

 Option B          

Explanation:

In simple words, Income inequality refers to the severe imbalance in wealth levels typically in the possession of a limited minority of a community with a large accumulation of wealth.

If wealth disparity exists, there is indeed a wide difference in the resources of one group of the society and that of another. Specific forms of discrimination and study of wage differences should be used to explain economic inequality.                      

          Thus, from the above we can conclude that the correct option is B .

Which of the following will not cause the production possibility frontier to shift? Group of answer choices the introduction of
algol13

Answer:

an increase in the working population

Explanation:

The Production possibilities frontier (PPF) is a curve that shows the various combination of two goods a company can produce when all its resources are fully utilised.  

The PPC is concave to the origin. This means that as more quantities of a product is produced, the fewer resources it has available to produce another good. As a result, less of the other product would be produced. So, the opportunity cost of producing a good increase as more and more of that good is produced.  

The PPF can shift either inward or outward.

An outward shift is associated with an increase in output while an inward shift is associated with a reduction in output.

Factors that cause the PPF to shift

1. changes in technology. technological progress leads to outward shift of the PPF. introduction of "fiber optic" technology would shift the PPF outward.

2. changes in available resources. a land reclamation program would increase the land available for production and this would increase output. While an explosion destroying a chemical plant would reduce output and lead to an inward shift of the PPF

3. changes in the labour force. A decrease in unemployment would increase output and shift the the PPF outward

Working population is the number of people between 15-59.
