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.

jeffery wei received a 6 year non subsidized student loan of 30000 at an annual interest rate of 5.2%. what are jeffery’s monthl
Anettt [7]
If the loan interest rate remains at i=5.2%/12 per month throughout the six years, 
then amount owing after 4 years, or the future value 
F=30000(1+i)^(4*12)
==30000(1+0.052/12)^(48)
=36919.80    to the nearest cent

Monthly payment, A, required to repay the loan in two years (24 months)
\frac{P(i*(1+i)^n)}{(1+i)^n-1}
=\frac{36919.80(.052/12*(1+.052/12)^{24})}{(1+.052/12)^{24}-1}
=1623.03  to the nearest cent.

Answer: Jeffrey will have to repay $1623.03 monthly during the last two years of his loan to owe nothing at the end of the 6 years loan period.
