Answer 000= 250 +. 75(4000) + 1000 -50r Er= 15 6250= 250 +. 75(5250) + 1000- 50r Public Saving = -250 Private Saving = 187. National Saving = -62. (I) Er = 21

Answer 1.
5000= 250 + .75(4000) + 1000 -50r
Er= 15
6250= 250 + .75(5250) + 1000- 50r
Public Saving = -250
Private Saving = 187.5
National Saving = -62.5 (I)
Er = 21.25
In the end, it turns out that the economic model is only valid in this form when the interest rate at stabilization falls somewhere in the range of 1,500 and 2,125 percent.
Answer 2.

GDP components.	Year 1 1950	Year 2 1980	Year 3 2016
Total GDP	279	2796.8	18407.4
Personal consumption expenditures	1360	3991.5	11572.1
Gross private domestic investment	56.5	530.1	3057.2
Government purchases	9.257	38.239	11
Net exports	0.7	-13.1	-521.2
Imports	11.6	293.8	2735.8

All of the subcomponents are on the rise, with the exception of one indicator called net export, which is on the fall. Since the import rate has increased in the three years that followed, NE has decreased, as shown in the chart, which indicates that this trend has been ongoing. In addition, it reveals that the professional rate in 2016 was a staggering 2,214.6. Over the course of each decade, there was a significant rise in GDP, which contributed to the overall growth and prosperity of the national economy.
