Answer:

Income elasticity of demand for snarfblatts is 1.

the consumer spends 20% of the income on snarfblatts, thus the percentage change in consumption of the snaerblatts is equal to the percentage in income, that is:

Elasticity = % change in demand of snarfblatts/% change in income

               = 1

Therefore, Income elasticity of demand for snarfblatts is 1.
