Answer:
Having invested $ 300 per month for the past 8 years, the total accumulated investment amount would be $ 28,800 (8 x 12 x 300). Now, having a total amount of $ 43,262, we find an increase of $ 14,462, which corresponds to the interest accumulated during said period. To know the percentage of the increase, we must perform a cross multiplication:
28,800 = 100
14,462 = X
(14,462 x 100) / 28,800 = X
1,446,200 / 28,800 = X
50.21 = X
As we can see, the investment had an increase of 50.21% during these 8 years. Now, the average increase in investment arises from the division of the total percentage of increase by the number of years. So, given that 50.21 / 8 = 6.27, the average annual return rate of this investment is 6.27%.
Answer:
Letter C is correct. <u>The Theory X style of management.</u>
Explanation:
The most suitable alternative is the letter C.<u> </u>The Theory X style of management.
Theory X can be defined as one of the currents of thought proposed by Douglas Mcgregor in 1960, and refers to assumptions about the behavior of employees in the workplace, this means that management must be developed from the actions and behaviors of employees , from there different styles of planning, controlling, organizing and dividing tasks will emerge.
In administration based on theory X, the individual is considered self-centered, without ambitions and needs supervision to exercise self-discipline and self-control. Economic benefits must be offered as a form of incentive and punishment.
According to theory X, employees avoid responsibility, so there must be economic incentives for them to be more ambitious and productive.
Answer:
prices to fall according to the classical economists and unemployment to increase according to Keynes.
Explanation:
The classical economists believes that a decrease in aggregate demand for goods produced would being about fall in the prices of such goods. What this implies is that as more goods are produced, if such production is not backed by corresponding demand by consumers, the prices of such goods produced will eventually fall because supply is greater than demand.
For the Keynes, their argument is that a decrease in aggregate demand will cause unemployment to increase. This is because owners of businesses or employers would lay off their employees when goods produced exceeds the demand for such production by consumers. Here, owners of businesses pays their employees through sales of goods produced. So, when the goods produced are not purchased, then there will be excess availability of such goods; hence no sale or profit, from which salaries would be paid. The next step is to start laying off employees because employers cannot cover their running costs.

Answer:
b. set in when the fifth worker is hired
After this point additional worker return will be lower.
Explanation:
Trhe diminishing return are the moment at which the marginal increase in production decrease.
In other words, adding a new resource provide less return than his predecessor.
Marginal
2 do 4 hours
3 do 6 houses (marginal 6 - 4 = 2)
4 do 9 houses (marginal 9 - 6 = 3)
5 do 13 houses (marginal 13 - 9 = 4)
6 do 15 houses (marginal 15 - 13 = 2)
the marginal output decrease from 4 to 2 the returns decreased.
