A consumer with the following utility function U = xy2 faces two constraints. The first is the normal budget constraint where he has GH¢150 and the price of x and y are both GH¢1. Also, the consumer has been issued 200 ration coupons by the government which he must use whenever he buys either x or y. It takes 2 coupons to buy an x and 1 coupon to buy a y (for example: to buy 3 units of x it would require GH¢3 or 6 coupons) (i) Write down the Lagrangian for this problem. (ii) Applying the steps of Kuhn-Tucker, find the optimal x and y. Identify which constraints, if any, are binding.

Enrique is a movie buff. He likes to watch on demand movies from his cable company, which cost $5 each, and so likes to go to the local movie house, which charges $15 a ticket. Suppose that given his budget and his tentative spending plans, the marginal utility from a cable movie is 15 utils and the marginal utility of a movie at the local cinema is 45 utils. Assuming he is spending his entire budget, Enrique is currently maximizing his utility Enrique can increase his utility by buying more cable movies and watching fewer cinema movies Enrique can increase his utility by buying more cinema movies and fewer cable movies

Sally the Sleek's preferences can be described by the utility function U(x, y) = x*y/1000. Prices are Px = 4 and py = 3; she has an income of $80 to spend. (a) If Sally initially consumed 5 units of x and 20 units of y, how much additional utility does she get from spending one small fraction of a dollar more on good x? How much additional utility does she get from spending one (small fraction of a) dollar more on good y? (b) By how much would her utility change if she stayed on the same budget and consumed 4 (small fractions of a) dollars worth more of x? Judging from this, can the allocation of x = 5 and y = 20 be optimal? (c) How much should Sally consume of x and y in order to maximize utility, given her income?
11) Stanley consumes only white and red wines and his utility function can be describedby U(R,W) = R0.40∙W0.60, where R is the number of bottles of red wine and W is the4number of bottles of white wine that he consumes per month. Suppose that his income is$500 and the price of a bottle of red wine $20 and the price of a bottle of white wine is$15. In this case, Stanley will purchase _____ bottles of red wine and _____ bottles ofwhite wine per month. Next, suppose that the price of red wine goes up to $35 per bottle.In this case, Stanley would consume ______ quantity of bottles of white wine comparedto the original situation.A) 10; 20; smallerB) 20; 10; smallerC) 10; 20; the sameD) 20; 10; the sameE) None of the above.
Utility Maximization. Suppose that an individual has a utility function given asU =√XYwhere U is the total utility, X is the quantity of good X that is consumed, and Y is the quantity ofgood Y consumed.It follows thatMUxMUy= X/Ywhere MUx is the marginal utility of X and MUy is the marginal utility of Y.The individual’s budget constraint isI = PxX + PyYwhere I is income, Px is the price of good X, and Py is the price of good Y.Suppose that Px = 2, Py = 1, and I = 100. How much of X and Y does this individual purchase?
Malcom only consumes 2 goods - Good A and Good B. His budget constraint is 4A+2B=400, which means Good A's cost is $4 per unit, Good B's cost is fixed at $2 per unit, and income is fixed at $400. However, Good A's cost is not fixed, with the condition that if Malcom consumes more than 5 units of Good A, Good A would cost him $5 per unit. Thus if he does consume more than 5 units of Good A, his budget constraint would be 5A+2B=400 (a). How does Malcom's optimal choice change? Explain in full detail. (b) How does Malcom's well-being change? Explain in full detail.

2. Tom spends all his $100 weekly income on two goods, apples and bananas. His utility function is given by U (A, B) = AB, where A and B stand for the quantity of apples and bananas consumed by Tom. If PA = $4 and PB= $10, how many apples and bananas will he consume? Make sure you write out the utility maximization problem explicitly, including the decision variable(s). What if his utility function is given by U (A, B) = A0.5B 0.5?
