-4.2

Explanation:

The income elasticity of demand determines the change in quantity demanded of a product due to change in income

The income elasticity of demand is calculate by:

Change in quantity demanded / change in price

(40 - 10) / [ (40+10) / 2] / ($30,000 - $40,000) / [ ($30,000 + $40,000) / 2]

= (30 / 25) / ($10,000 / $35,000)

1.2 / 285.7 = - 4.2
