Grace is a grandmother who is looking for a long-range investment for her grandchild Elliott’s education. I searched the internet to find a Certificate of Deposit, which is a CD plan that earns compounded interest to invest her $25,000.

I used the advertised rates, the number of compounding periods per year and the time the funds will be invested, from the web site I researched to calculate the future value of her investment. Here is a step by step walk through of how I calculated Grace’s future investment.

Tip: You’re going to need a special calculator to apply your values and get the correct result. The calculator I used was at the following website:

Retrieved from https://www.bankoncit.com/calculators-savings.htm

Step #1. Was to apply the principle investment $25,000.
The principal is $25,000 Principle =P P=$25,000

Step #2. Was to apply the advertised annual interest rate for her investment. Remember to convert your percent to a decimal dividing it by 100

Use advertised annual interest rate from the website

Step #3. Was to apply the time in years for the investment.
State the time in years for the investment.

Time in years = t T=10

In this scenario we were not given the number of compounding periods a year. That means you’ll have to make it up.

Some options you may choose would be: Annual, Quarterly, Monthly or Daily. I chose annual because it made the math simple for me making the value for (n) #1.

Step #4. Was to apply the number of compounding periods per year. State Compounding Periods Per Year which will =(n)

Compounded Periods = 1 (Annual) N=1

Now I’ll put the assigned values in a simple column for easy reading going into the next step.

P=$25,000
R=0.0115
T=10
N=1

Step #5. Now we can apply these values to the formula F(t) = P(1 + r/n) nt...

a.
e^(0.05t)=1600
Answer: t=147.556
Show your work:
ln(e^(0.05t))=ln(1600)
0.05t=ln(1600)
(0.05t)/(0.05)=(ln(1600))/(0.05)
t=(ln(1600))/(0.05)
t=20ln(1600)
t=147.556

Answer:
After 4 months:
54.02%
After 24 months:
40.04%
Show work:
S (4) = 68 – 20 * log (4 + 1) = 54.02
S (24) = 68 – 20 * log (24 + 1) = 40.04

I have put a side 62,000 for my grandsons college tuition and I have found that the best most safe and effective way to earn money for the next 12 yrs until he goes to college is by investing it into a CD with an annual rate of 0 .90% (bankrate, 2013) and it is compounded monthly.
I have researched to see if my investment would help with tuition in 12 years. I used an inflation calculator and with the current trend of 45% increases in college tuition per year in 12 years college will cost 99,900.49 in the first year and 8% inflation increase each year after. This was done for a 4yrs public college (College Cost Projecter, 2013).
My Principal starting fund in 2013 grandson age 6 is $62,000.
a) Annual Interest rate r= 0.90%
b) Investment time t= 18yrs
c) Interest compounded monthly n=12
d) Model of my investment earns as a function is f(t)=P(1+r/n)^nt f(12)=62,000(1+.009/12)^12t
f(12)= 62,000(1+.009/12)^12*12
f(12)=62000(1+.00075)^12*12
f(12)=62000(1.00075)^12*12
f(12)=62000(1.00075)^144
f(12)=62000*144.108
f(12)=89,346.96 Future value of my investment
With the average cost of college today (National Center for Education Statistics, 2013) , I have found that I would have enough money for the first two years of college, if he were going today. In the future I would have enough for a portion of the first year. If available he...

Eventually I was employed in the private sector, where I have worked ever since. I am currently employed as the nursery teacher in the pre-school room. I feel that I am able to pass on my knowledge to the other practitioners in the setting, which in turn helps them to improve their practice.
I am now at the stage in my life where I feel that I would like to move out of the rooms and work on the management side. Therefore I have decided to retrain by completing this level 5 qualification to enable me to improve my knowledge of the management of a nursery setting, and to become a competent Deputy Manager.
3.Be able to prepare a professional development plan
3.1 – Select learning opportunities to meet development objectives and reflect personal learning style
There are three different learning styles. Auditory, whereby the learner is able to listen to explanations. Visual, where the learning takes place by looking at graphics, watching demonstrations or reading, and finally Kinestheic, where the learner processes the information through a hands on experience, by doing the activity, or writing notes to help them to understand.
Most learners use a combination of all 3 styles, but have a clear preference for one. My preferred style is kinaesthetic. I prefer to ‘do’ something in order to understand. I find sitting being lectured to very difficult, therefore I take constant notes to keep my...
