B. oligopolistic firms act independently while competitive firms operate interdependently.

Explanation:

A perfect competition is characterised by many buyers and sellers of homogenous goods and services produced in an economy within a given period which is usually a year. Market prices are set by the forces of demand and supply.

An oligopoly is characterised by few large firms. Firms in an oligopoly usually come together collusively to either set the prices or the quantity to be supplied in order to earn higher profits.

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"
