Rhea is determining how many gallons of milk (M) and loaves of bread (B) to purchase. Use the information in italics to answer the bolded question below: • Rhea's marginal utility function for milk: 1 MUM = 0.5MB Rhea's marginal utility function for bread: MUB = 0.5MB- Rhea has $60 to spend on bread and milk. • The price of milk (Pm) is $3/gallon of milk. • The price of bread (Pb) is $1/loaf of bread. • For the sake of computation, assume that bread is the horizontal axis good (i.e., good X) and milk is the vertical axis good (i.e., good Y). Consider Bundle A: (B, M) = (12 loaves, 16 gallons). 1. If bread is the horizontal axis good, what is Rhea's marginal rate of substitution at bundle A? [Select] 1 [Select 1 ✪ II. Given her budget constraint, what should she do to increase her utility?
I. A)MRS=1/3, B)MRS=1/4, C)MRS=4/3, D)MRS=12
II. A)Rhea should buy more bread, less milk, B)Rhea should buy more milk, less bread, C) Rhea maximizes her utility at bundle A, so she should not change her consumptions of either good, D) Rhea cannot afford bundle A, so she should buy less of both goods
III. A)Rhea's MRS at bundle A is greater than the
Consumer utility is derived by the consumption of goods and services with given level of income and price.
And the maximum utility is gained when consumer attains equilibrium point .
