For certain goods called necessities, demand is not related to income. Demand for salt does not increase with the increase in income & does not decrease with the decrease in income. It means that it is irrespective of income. The demand curve slopes downward for goods like salt, but it is inelastic.

Fixed costs are business expenses that are not dependent on the level of goods or services produced by the business. They tend to be time-related, such as salaries or rents being paid per month, and are often referred to as overhead costs. This is in contrast to variable costs, which are volume-related (and are paid per quantity produced).

Correct Option: D

Average fixed cost refers to fixed costs of production (FC) divided by the quantity (Q) of output produced. It is a per-unit-of-output measure of fixed costs. As the total number of goods produced increases, the average fixed cost decreases because the same amount of fixed costs is being spread over a larger number of units of output.

Correct Option: B

Average fixed cost refers to fixed costs of production (FC) divided by the quantity (Q) of output produced. It is a per-unit-of-output measure of fixed costs. As the total number of goods produced increases, the average fixed cost decreases because the same amount of fixed costs is being spread over a larger number of units of output.

Law of demand states that consumers buy more of a good when its price is lower and less when its price is higher. It states that the quantity demanded and the prices of a commodity are inversely related, other things remaining constant. That is, if the income of the consumer, prices of the related goods, and preferences of the consumer remain unchanged, then the change in quantity of good demanded by the consumer will be negatively correlated to the change in the price of the good.

Price elasticity of demand (PED or Ed) is a measure used in economics to show the responsiveness, or elasticity, of the quantity demanded of a good or service to a change in its price. A decrease in the price of a good normally results in an increase in the quantity demanded by consumers because of the law of demand, and conversely, quantity demanded decreases when price rises. So, here the decrease in price of Pepsi will increase in demand for it, while the demand for Coke and 7-Up will decrease because of no change in their price level.
