Assume that a 6 percent increase in income in the economy produces a 3 percent increase in the quantity demanded of good X. The coefficient of income elasticity of demand is: a. negative and therefore X is an inferior good.
b. negative and therefore X is a normal good.
c. positive and therefore X is an inferior good.
d. positive and therefore X is a normal good.

d. positive and therefore X is a normal good.

Explanation:

As we know that

And, the income elasticity of demand would equal to

= (Percentage Change in quantity demanded) ÷ (Percentage Change in income)

= (3%) ÷ (6%)

= 0.5

As we see that the income elasticity of demand is positive and 0.5 that represents the goods are normal goods as it depicts a positive relationship between the income and quantity demanded plus the elasticity also comes in positive.              

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"
