Sudi spends his income on two goods. His income elasticity of demand for the first good is \(\xi_{1}=0.2\), while his income elasticity of demand for the second good is \(\xi_{1}=2\). Illustrate in one diagram how a \(10 \%\) increase in his income would affect the quantity he demands of the two goods that shows an income consumption curve, and create another diagram for each of the two goods that shows an Engel curve. How do the slopes of the Engel curves compare?
