Consider a consumer in a two commodity world whose indifference map is such that the slope of the indifference curves is everywhere equal to -(Y?X), where Y is the quantity of good Y measured along the vertical axis, and X is the quantity of good X measured along the horizontal axis.

a. what is the value of the optimum Marginal Rate of Substitution for this consumer, given that the price of X is $1, the price of Y is $3 and the consumer's income is $120?

b. How much X ands Y will be consumed?

c. Explain, with the aid of a graph, what would happen to the consumption of X if its prices rose to $2, everything else constant?

    Question 9 1 pts Logan Roy is spending all his money income by buying mineral water and popcorn. At his current consumption level, the marginal utility of mineral water is 70 and the marginal utility of popcorn is 60. The price of a bottle of mineral water is $2.00 and the price of a box of popcorn is $1.50. The utility-maximizing rule suggests that Logan should: O Increase consumption of popcorn and increase consumption of mineral water Decrease consumption of...
