1) Kamal has ₹50 income and consumes MP3s and samosas. Price of an MP3 is ₹1 per song. Price of a samosa is ₹5. In equilibrium Kamal consumes 25MP3 s and 5 samosas. Please answer the following questions. a) Draw the budget line, indifference curve, and show the equilibrium clearly pointing everything out with MP3s on the horizontal axis and samosas on the vertical axis. b) What is the marginal rate of substitution in equilibrium? c) What if Kamal consumes 10MP3 s and 3 samosas? d) Extra Credit: If Kamal's utility function is =axα y (1−α), where a=2,α=0.5,x= quantity of MP3 consumed, y= quantity of samosa consumed, then do we indeed have an equilibrium at (x∗,y ∗)=(25,5) ?
