Borrow Money..
My friend who the name is X, has borrowed money from me which amount RM10.00. Then I decide to charges her using simple interest rate. The rate is 12% and i give her 1 week to settle back.
Using the Formula:I=Prt
P=10
r=12%
t=7/360
What is the amount, she should pa me back?

Calculate Simple Interest, Principal, Rate or Time when 3 Values are Known
When you know the principal amount, the rate and the time. The amount of interest can be calculated by using the formula:I = Prt

Simple Interest
The basic definitions required for someone to understand the concept are:
1. Principal - the initial amount of the debt, usually the price of the item purchased.
2. Interest Rate - the amount one will pay for the use of someone else's money. Usually expressed as a percentage so that this amount can be expressed for any period of time.
3. Time- essentially the amount of time that will be taken to pay down (eliminate) the debt. Usually expressed in years, but best understood as the number of and interval of payments, i.e., 36 monthly payments.
Simple interest calculation follows the formula:
I= PRT, where
I=Interest
P=Principal
R= Interest Rate
T= Time.
The challenge: John decides to buy a car. The dealer gives him a price and tells him he can pay on time as long as he makes 36 installments and agrees to pay six per cent interest. (6%). The facts are:
Agreed price 18,000 for the car, taxes included.
3 years or 36 equal payments to pay out the debt.
Interest rate of 6%.
The first payment will occur 30 days after receiving the loan
A simple timeline will give you an idea of the question we need to address.
. To simplify the problem, we know the following:
1. The monthly payment will include at least 1/36th of the principal so we can pay off the original debt.
2. The monthly payment will also include an interest component that is equal to 1/36 of the total interest.
3. Total interest is calculated by looking at a series of varying amounts at a fixed interest rate.
Take a look at this chart reflecting our loan scenario.
By totaling the amount of interest and calculating the average, you can arrive at a simple estimation of the payment required to amortize this debt. Averaging will differ from exact because you are paying less than the actual calculated amount of interest for the early payments, which would change the amount of the outstanding balance and therefore the amount of interest calculated for the next period.
Understanding the simple effect of interest on an amount in terms of a a given time period and realizing that amortization is nothing more then a progressive summary of a series of simple monthly debt calculations should provide a person with a better understanding of loans and mortgages. The math is both simple and complex; calculating the periodic interest is simple but finding the exact periodic payment to amortize the debt is complex.

MathBlog
Business mathematics is mathematics used by commercial enterprises to record and manage business operations. Mathematics typically used in commerce includes elementary arithmetic, such as fractions, decimals, and percentages, elementary algebra, statistics and probability. Business management can be made more effective in some cases by use of more advanced mathematics such as calculus, matrix algebra and linear programming.
Commercial organizations use mathematics in accounting, inventory management, marketing, sales forecasting, and financial analysis.
