A) good is a normal good.
B) good is an inferior good.
C) income elasticity of demand is 0.5. D) income elasticity of demand is 2.0. E) income elasticity of demand is 5.0.

48. If the given elasticity of demand for trip to Vermont is greater than 1, then it is a normal good under which it can be categorized as luxury good or a superior good.

49 Income Elasticity Ed = %Change in Qty demanded/%Change in income

=-10/5 = -2
