The law of diminishing marginal utility allows us to conclude that A) demand curves slope downward to the right. B) total utility will increase by an increasing amount as consumption increases. C) supply curves slope upward. D) a consumer will buy positive amounts of all goods.

Suppose that, by law, a person is required to consume a fixed amount of good X, say X0.  Assuming X is a normal good, explain how this law reduces utility for both high and low income people.

A student has a lunch utility function U(S, P) 8S + 3P, where S is number of salads per month and P is number of pizzas per month. The price of a salad is $5, the price of a pizza is 8, and his monthly income for lunch is $80. a) Derive the equation representing the consumer's demand for Salad. Represent the demand for Salad graphically. b) The price of Salad goes up to $25 and the price of Pizza does not change. Compute and represent graphically the new equilibrium of the student. What can you tell about the substitution effect on Salad and pizza

Assume one person has the following utility function : = x f yz and the total income y 2 xpx+ yPy + zpz u( x, y, z, What are the values of income (y) and prices (px.Py,Pz) will be when a person's demand strictly positive quantity of good x?

Utility is a type of function that occurs in economics. When a consumer receives x units of a certain product, a certain amount of pleasure, or utility U, is derived. The graph represents a typical utility function. a) Find the average rate of change of U as x changes from 0 to 1; from 1 to 2; from 2 to 3; from 3 to 4. b) Why do the average rates of change decrease as x increases? a) The average rate of change of U as x changes from 0 to 1 is. (Type an integer or a decimal.) C Utility (pleasure units) AU 200- 150- 100- 50- 0 (1,67) (2,106) I (3,134) (4,156) 2 Number of units of product 4 X

Utility maximization with a budget constraint. A hypothetical consumer spends all tgheir income on ramen noodles (N) and wild rice (W). N is the quantity of noodles; W is the quantity of wild rice. Their income is $1,600 per month. the price of noodles is $2 per package and the price of wild rice is $20 per pound. The utility function is U=sqrt(N*W).   the MRS = -N/W.   The budget constraint is: 1,600 = 2*N + 20*W   Graph Qty of noodles (N) on vertical axis and Qty of wild rice (W) on horizontal axis.   SOLVE: a. Graph the budget constraint. label all points. What is the slope of the budget constraint? b. Find the optimal quantities of noodles(# of packages) and the wild rice (# of pounds) given the budget constraint. graph these optimal quantities. draw your indifference curve on the same graph. c. Show on your graph what happens when the price of wild rice increases to $40 per pound. Find your new optimal quantities of noodles and wild rice. label all points on graph. label the…
