Answer:
Check Explanation
Step-by-step explanation:
In finance, the rule of 70 estimates how long incomes take to double.
(Number of years it takes for income to
double) = 70/(annual percentage growth rate)
a) At 2.8%
N = (70/2.8) = 25.0 years
It will take 25.0 years for incomes to double.
b) At 4.6%
N = (70/4.6) = 15.2 years
It will take 15.2 years for incomes to double.
c) At 6.3%
N = (70/6.3) = 11.1 years
It will take 11.1 years for incomes to double.
d) At 7.8%
N = (70/7.8) = 9.0 years
It will take 9.0 years for incomes to double.
e) At 8.9%
N = (70/8.9) = 7.9 years
It will take 7.9 years for incomes to double.
