Question 4. Suppose Milton has $140 to be divided optimally between corn and beans. What will be the relationship between the price of beans and the amount of beans he will buy if U = 18In Qe + 2 In Qn. where U is his utility, Qc is the quantity of corn he consumes (in pounds). and Qu is the quantity of beans he consumes (in pounds)?[ (Hint: You are asked to derive an equation between Qa and Py using the tangency condition and the budget line. Notice that the relationship you will find is actually the demand function or demand curve for beans.)
