a) Do the preferences indicated diminishing marginal utility for Xand Y?
b) If john has income of 30 dollars. What is his demandcurve/equation for X when the price of Y is 2 dollars.
c) If the price of x is 1 dollar and price of y is 2 dollars, what is the equation of John's income-consumption curve?
