## Question:

Suppose that you know the utility function for an individual is given by the equation {eq}U = XY {/eq} where {eq}U {/eq} is the total amount of utility the individual gets when they consume good {eq}X {/eq} and good {eq}Y {/eq}. You are also told that this individual's income is $100 and that the price of good {eq}X {/eq} is $2 and the price of good {eq}Y {/eq} is $4. From this information answer the following set of questions.

a) What is the consumption bundle of good {eq}X {/eq} and good {eq}Y {/eq} that maximizes this individual's utility given their income, prices of the two goods, and their tastes and preferences as measured by their utility function? Support your answer with a well-labeled diagram.

b) What is the level of utility this individual gets when they maximize their utility given the above information?

c) Suppose that the price of good {eq}X {/eq} increases to {eq}$4 {/eq} and nothing else changes. What is the new consumption bundle that maximizes the individual's utility now that the price of good {eq}X {/eq} has increased? What has happened to his utility? Determine the {eq}SE {/eq} and {eq}IE {/eq}.

## Utility function

Utility function is the function which show the satisfaction derived from the consumption of the commodity concerned with the constrained budget. This function shows a negative value when the consumption is more than the optimum level.
