Payback Method The payback method is useful because of its simplicity. You simply take the expected cash inflows per year expected after the initial investment and find the breakeven point in where the cash inflows equals the initial investment. Whenever that breakeven point occurs on your timeline‚ that is your payback period. Let us suppose an initial investment for a project is $1.3 million‚ the expected cash inflows for the first two years totals $850‚000‚ and the third year is expected to

hypothesis or question using a systematic method to discover an answer. The key to the concept of research as opposed to simply guessing at answers is the systematic approach it employs. This systematic approach is commonly referred to as the Scientific Method. Without the Scientific Method research would loose its validity because there would be no controls in place to make sure you are measuring or evaluating what you actually set out to find. The scientific method usually begins with some background

Accrual Method Nonprofit organizations are required to produce financial statements based on the accrual method of accounting. How is this different from the cash basis of accounting?

The method combines the reactions of copper ions with the peptide bonds under alkaline conditions (the Biuret test) with the oxidation of aromatic protein residues. The Lowry method is best used with protein concentrations of 0.01–1.0 mg/mL and is based on the reaction of Cu+‚ produced by the oxidation of peptide bonds‚ with Folin–Ciocalteu reagent (a
