Assume that a consumer spends all his income in the purchase of two commodities X and Y whose prices are Ksh.30 and Ksh.20 per unit respectively. The consumer’s monthly income is Ksh.12000. He is satisfied with various combinations of X and Y but prefers to spend his income in equal proportions on the commodities, that is, at a ratio of 1:1 to maintain his level of satisfaction.

(ii) What is the effect of an increase in the consumer’s income from Ksh.12000
to Ksh.24000 per month
