Suppose That the Price of Gasoline Has Risen by 50

Essay

Suppose that the price of gasoline has risen by 50%. What happens to a consumer's level of well-being given he spends some of his income on gasoline? Diagram the impact of the increase in gas prices in a commodity space diagram, and show the relevant indifference curves.
Now, if the individual's income rises just enough so that his original consumption bundle exactly exhausts his income, will the individual purchase more or less gasoline (this level of income implies the consumer can afford his original consumption bundle)?
