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 would have to get loans, grants and scholarships in the future. I hope that future costs of college will not deter students from attending. References

ANALYSIS
Physics has a lot of topics to cover. In the previous experiments, we discussed Forces, Kinematics, and Motions. In this experiment, the focus is all about Friction. Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction like fluid friction which describes the friction between layers of a viscous fluid that are moving relative to each other; dry friction which resists relative lateral motion of two solid surfaces in contact and is subdivided into static friction between non-moving surfaces, and kinetic friction between moving surfaces; lubricated friction which is a case of fluid friction where a fluid separates two solid surfaces; skin friction which is a component of drag, the force resisting the motion of a fluid across the surface of a body; internal friction is the force resisting motion between the elements making up a solid material while it undergoes deformation and sliding friction.
When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into heat. This property can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire. Kinetic energy is converted to heat whenever motion with friction occurs, for example when a viscous fluid is stirred. Another important consequence of many types of friction can be wear,...

The case between Beauty and Stylish involves concept of a valid contract, pre-contractual statements, express term and misrepresentation.
A valid contract is established between Beauty and Stylish when an offer is accepted and there is intention for both parties to create legal relations. An offer refers to the expression of willingness of the offerer to be contractually bound by an agreement if his or her offer is properly accepted. It has to be clear and certain in terms. It must also be communicated to the offeree before it is being accepted. In addition, the acceptance has to be unqualified, unconditional and made by a positive act. In the case of Beauty and Stylish, a positive act refers to the signing of the contract. All terms of the offer must be accepted without any changes and cannot be subjected to any condition, taking effect only upon fulfillment of that condition. When Beauty and Stylish enter into the agreement, they must intend to bind and bound legally to each other by their agreement. This is the intention to create legal relations between two parties. In the meanwhile, this contract must possess consideration. A contract must therefore be a two-sided affair, with each side providing or promising to provide something of value in exchange for what the other is to provide.
Every contract, whether oral or written, contain terms. The terms of a contract set out the rights and duties of the parties. Terms are the promises and undertakings given by each...

Credit and Loans:
Simple Interest and Flat Rate Loans:
A flat rate loan is one where flat or simple interest is charged on an amount borrowed or principal for the term of the loan. Interest is always charged on the full amount of the loan.
I = Prn
P = principal
r = rate per period expressed as a decimal
n = number of periods
E.g. Phil borrowed $4000 for three years at 8%p.a. (per annum) (flat rate)
a) What is his interest?
b) What is the total repaid?
c) What are the monthly repayments?
Solution:
a) 4000x8/100x3
Interest=$960
b) Total Repaid: interest + principal
=960+4000
=$4960
c) Monthly repayments:
=4960÷36 (36 is the number of months is 3yrs)
=137.777……
=137.78
Buying on Terms:
- Time payment- agreement to pay for goods over a certain period of time
- This is also called a hire purchase as the customer actually hires (borrows) the good until they are paid off.
- Goods can be reposed if payments are failed to be paid
- Deferred Payment Plan- deposit, ‘interest-free period’,
E.g. Jem borrowed $200 at $120 per month for two years. He also paid $300 deposit
A) What was the cash price of the item
=$2300
B) What did he pay in total?
= 120x24+300
=$3180
C) What was the flat interest rate?
= Int= 3180-2300
=$880
=Rate: I=PRN
=880=2000xrx2 (2 means years of interest rate in % p.a.)
r=880÷2000÷2

...• What were the most revolutionary social and economic developments of the last quarter of the nineteenth century?
• How did different groups of Americans respond to those changes and how effective were their responses?
• What role did government play in these developments?
In the late 1900s some of the most social and economic developments were railroads, steel oil, the type writer cash register, light bulb and agriculture. The development of the railroad made it easier for immigrant to come to this country for work. This meant that there were more group of different races and cultures in America. And in some states there became an over population and city workers like police and garbage men could not keep up with the demand of so many people. Some groups mover to open land for the Homestead Act. They had hope of farming and staying on the land for at least five years as agreed but the supply and demand of agriculture did sustain so many farmer moved off the land well before their five years. The government played many different role I deescalating some issues in American history. Women and children were being worked for long hours and getting paid a little bit of nothing in return for their hard work. So the government put labor laws into place that were to protect women and children. As oil, steel and railroad industries grew so did the levels of pollution. The government again put laws that were to protect animals and the earth so that there would not...
