The interest he needs to pay $494546.986 after 30 years.
Step-by-step explanation:
Given,
Principal (P) = $195000
Rate of interest (R) = 4.3%
Time (T) = 30 years
To find the amount he needs to pay after 30 years.
Formula
A = P
Now,
Putting,
P = 195000, T = 30 and R = 4.3 we get,
A = 195000
= 689546.986
So,
The interest he needs to pay = $(689546.986-195000)
= $494546.986
Answer:
A) In 2004 the population will reach 306 million.
B) In 2033 the population will reach 386 million.
Step-by-step explanation:
Given : The population of a certain country in 1996 was 286 million people. In addition, the population of the country was growing at a rate of 0.8% per year. Assuming that this growth rate continues, the model represents the population P (in millions of people) in year t.
To find : According to this model, when will the population of the country reach A. 306 million? B. 386 million?
Solution :
The model represent the population is
Where, P represents the population in million.
t represents the time.
A) When population P=306 million.
Taking log both side,
Therefore, In 2004 the population will reach 306 million.
B) When population P=386 million.
Taking log both side,
Therefore, In 2033 the population will reach 386 million.
