Amonopoly firm is the only seller of a good or service that a) does not need to be advertised. b) has no close complements c) does not have a close substitute. d) has a perfectly elastic demand.

C) does not have a close substitute.

Explanation:

A monopoly is a market structure where there is only a single seller but many buyers. The seller therefore has more bargaining power over buyers and is therefore the price maker; a monopolist decides and sets the price of the product. Since there is only one seller, it means that the good does not have close substitutes. However, a multi-product monopolist could sell goods or services that are close complements.

d, conspicuous consumption is when you try to increase your wealth or social status (and in the case he's trying to create the perception of wealth considering he can't really afford it)

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
