Answer:
Balance after 30 years = $151,018.50
Explanation:
In order to calculate this, we will calculate the future value on an amount invested, gaining interest over the years of investment, and this is given by:

where:
FV = future value
PV = present value
r = interest rate
t = time in years.
Hence the future value is calculated as follows:
1. For the first 10 years at 7% interest:
7% interest = 7/100 = 0.07


2. For the last 20 years at 9.5%(0.095) interest:
Note that for the remaining 20 years, the present value (PV) used = 24,589.392, as ending balance after the first 10 years


Total Future value earned = $151,018.50

A. True the answer is not false
Answer:
Instructions are below.
Explanation:
Giving the following information:
Susan:
Annual deposit= $5,000 for 10 years
Lumo-sum for 30 years
Interest rate= 8.5%
Jane:
Annual deposit= $5,000 for 30 years.
<u>First, we will calculate the future value of Susan:</u>
<u></u>
First 10 years:
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
FV= {5,000*[(1.085^10)-1]}/0.085
FV= $74,175.50
Last 30 years:
FV= PV*(1+i)^n
FV= 74,175.50*(1.085^30)
FV= $857,050.14
<u>Jane:</u>
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
FV= {5,000*[(1.085^30)-1]}/0.085
FV= $621,073.63
<u>Earnings difference= 857,050.14 - 621,073.63= $235,976.51 in favor of Susan.</u>
