D.

Explanation:

It can be said that consumers are not always only interested on themselves in a material sense, many times they are also concerned with fairness as exemplified by tipping in restaurants that will never be visited again. If they were only concerned with themselves they would not tip at a restaurant and instead hold onto that money and use it later for something that they themselves would want.

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"

answer(eu) is the correct answer;
