Explanation:

Competition in the markets refers to the rivalry among businesses selling similar products to the same customers. Each business tries to find the best tactics to win more customers, make more revenues, or acquire a larger market share.

In a free-market economy, there are no restrictions on the number of businesses in an industry. The market will usually have many buyers and sellers. The sellers have to be creative and innovative to win more customers in a competitive environment. They develop and improve their products to gain a competitive advantage. In the end, consumers benefit due to the availability of a variety of quality goods at reasonable prices.

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"
