Demonstration of Various Compounding
n (# of payments per year) p (Name of payment type) p (final principal)
Situation: A person initially borrows an amount A and in return agrees to make n repayments per year, each of an amount P. While the person is repaying the loan, interest is accumulating at an annual percentage rate of r, and this interest is compounded n times a year (along with each payment). Therefore, the person must continue paying these installments of amount P until the original amount and any accumulated interest is repayed. This equation gives the amount B that the person still needs to repay after t years.
Residual Value - also can be stated as Salvage Value, what is the value of a fixed asset after it has fully depreciated, or at the end of its useful life. http://www.investopedia.com/terms/r/residual-value.asp
Useful Life - is an estimate of how long something can be expected to be useful to the business (not how long it will actually last) The IRS defines "useful life" for estimating the amount of time over which an asset can be depreciated. InvestOpedia has a great dictionary http://www.investopedia.com/terms/u/usefullife.asp
Book Value - the value of the asset. Each year after depreciation, it is theoretical value of an asset if it were to be sold. http://www.investopedia.com/terms/b/bookvalue.asp
Depreciation - http://www.scribd.com/doc/47730829/Depreciation is a systematic and rational process of distributing the cost of tangible assets over the life of assets. Depreciation is a process of allocation. Cost to be allocated = acquisition cost - salvage value Allocated over the estimated useful life of assets. Allocation method should be systematic and rational.
Expected risk premium on stock = beta X expected risk premium on market
where rm = Expected rate of return on market portfolio
Suppose you are asked what the value 'of the common stock' is...
How you would calculate this net rate of return is a business question.

I like the way these were explained - and links to definitional and more examples:

Free Book: Safari Books on-Line
Lots of good examples from North Carolina State University's Math faculty

Profit = Revenue (or income) - Cost (or expenses) P=R-C or P = I - E
Total Profit = Total Revenue - Total Cost P = TR - TC
usually you will have limits included, like time, factory space, people, etc.

EX. a 5 gallon container of gas that lost a gallon of gas what percentage of gas did it loos?
1/5 = 5/100 or 1/5 * 100 = % --> 1(100)/5 = 20%
