Extracted text: Question 3 a. Andre has a salary of $1000. He spends his entire budget on shoes and beers. The cost for a pair of shoes is $15 and the cost for can of beer is $25. į. Construct Andre's budget constraint (place) beers on the y-axis. i. Suppose Andre's salary rises by 25%. Also suppose that the price of shoes and beers each rise by 40%. Construct Andre's new budget constraint. What is the difference between the new and old budget constraints? i. Suppose that the price of beers fell from $25 per beer to $15. Construct Andre's new budget constraint. What is the difference between the new and old budget constraints. b. Explain the relationship between the budget constraint and indifference curve at consumer optimum.
