1. Final Return over annual invest
a) The following are given amounts
P=$1, t=35 years, r=8% = 0.08, n=12
b) The given amounts are:
P=$1000, t=35 years, r=8% = 0.08, n=12
c) The investing amount is, P = $ 20,000

2. d) Effective wild is the unit calculation amount, which can be multiplied to the
invested amount to give the final amount. So it is useful for short cut the
calculation.
2. We have to calculate the number amount for a given time period:
a) 1 YEAR
P=$4000, r=10% = 0.10, and n = 4
b) 5YEAR
c) 20 YEAR
d)

3. P=$4000, r=10% = 0.10, and n = 4

a. Amount investing each year.
A (t) =$ 1296 .00
b. Determine the formula.
Solution:
The formula for accumulated amount is;
c. Graph this function from t = 0 to t = 50.

4. f. Age at retirement.
Solution:
Calculating we get, t=35 plus the age at doing job=25
Age = 35+25 =60
g. Money at the time of Retirement.
At the age of 60, I will have 35 years of saving; t=35
h. Interest amount.
Interest= Total- Investment
For 35 years investing $1200 per year,
i. Delay on investing
 1 year :
Total investment in 39 years is,
 5 year:

5. Total investment in 35 years is,
 10 year :
Total investment in 30 years is,
j. Amount I have on each year.
Solution:
I got at retirement. Planning to live 90 years
After 25 year the amount will be;
k. Solution:
In the next 25 years to live, the total is;
The amount is $ 109513.43 .

6. Solution: From (i), we get the value of C(t) is:
Hence, P =$ 391.43

n. Project Summary
Solution:
To estimate the future saving, we must need to calculate the amount
investing each month. The formula gives us better to accumulate the final
total at the time of retirement. This project is very good demonstration of the
retirement plan.
