Business Profit Analysis: Case Study Calculations
a) Define Fixed Costs
Fixed costs are expenses that do not change with the level of output or sales volume in the short run. Razia must pay for items such as her car lease, insurance, and other overheads even if she runs fewer courses.
b) Define Sales Volume
Sales volume is the total quantity of units sold by a business during a specific period. In this case, the unit is a 1-day training course; Razia sold 200 courses in 2016 and 150 courses in 2017.
c) Calculate the 2016 Business Profit
Revenue: 200

Say’s Law of Markets
Formulated by the French economist Jean-Baptiste Say, Say’s Law forms the absolute foundation of Classical economic thought. The law is famously summarized as:
“Supply creates its own demand.”

Native American Oral Traditions
Native American literature before colonization was entirely oral. Knowledge, beliefs, and history were transmitted by storytellers, who adapted the tales freely, creating multiple versions. Many stories were lost after the extermination and displacement of Indigenous peoples. The narratives served two main purposes: entertainment and didactic instruction, teaching proper behavior, cultural values, and the tribe’s worldview.
These stories usually take place in a mythical

English Phonology and Phonetics: Principles and Practice
Phonology and Phonetics: Understanding Speech Sounds
Phonology studies the abstract and functional role of sounds in a language, whereas phonetics studies the actual production, transmission, and perception of speech sounds. The basic unit in phonology is the phoneme, the smallest distinctive sound unit capable of changing meaning. If one phoneme changes, the meaning changes (e.g., price/prize, full/fool). A minimal pair consists of two words differing in only one phoneme, while a minimal set contains

Understanding Stock Valuation
A stock is worth the present value of its expected future income. Using the dividend growth model, that future income is primarily future dividends. The formula is: Stock Value = Present Value of Future Dividends.
Calculating Total Return
A stock provides returns in two ways:
- Dividend Yield: Cash paid by the company while you own the stock.
- Capital Gains Yield: Profit earned if the stock price increases.
Total Return = Dividend Yield + Capital Gains Yield
