What is demand
The quantity of a good or service that consumers are willing and able to buy at any given price in a given time period.
What is the law of demand
The inverse relationship between quantity demanded and the price of a good or service, ceteris paribus
What is diminishing marginal utility
An individual gains less extra satisfaction from consuming a product as each extra unit is consumed. This helps explain why demand curve is downward sloping. Meaning the consumer will be prepared to pay a progressively lower price for each additional unit of consumption.
Why is demand curve downward sloping
There is an inverse relationship between the price and the quantity demanded
For PCADC what would P-up QD-Down cause
Contraction in D
For PCADC what would P-Down QD-Up cause
Extension in D
Non price factors affecting demand
P-population-change in number and age distribution of potential buyers.
I-Income-change in income.
C-Complimentary goods- Change in price of the linked good.

What is a normal good
A good where the quantity demanded increases in response to an increase in consumer income. (↑Y = ↑D),(↓Y = ↓D)
What is a luxury good
A good where as income rises, consumers spend proportionally more on the good.
What is necessity good
A good where as income rises, consumers spend proportionally less on good.
What is an inferior good
A good where the quantity demanded decreases in response to an increase in consumer incomes. (↑Y = ↓D),(↓Y = ↑D)
What is a complementary good
A good where an increase in the price of another good causes its demand to fall.
e.g increase in P of good A = decrease in D of good B
Decrease in P of good A = Increase in D of good B
Example of complementary goods
Fish and chips, tennis balls and tennis rackets.
As a result of tastes and preferences
Consumer are W and A to buy more or less of the good.
