Amadea spends all her income on pizza,chocolate milk, and music streams. The price of pizza is $4 per slice and price ofchocolate milk $2 per bottle. At Amadea's current consumption level, her marginalutility for pizza is 50 units per slice and for music 100 units per stream. Assuming thatAmadea is a utility maximizer, how much is
(a)her current marginal utility for a bottleof chocolate milk, and
(b) the price of streams she buys. Show your work.
[Hint: Ch 6:Utility-maximizing formula)
Give typing answer with explanation and conclusion
Suppose that a consumer's utility function is U=x^5*y^3*z^3, where x is the consumption of mineral water, y is the consumption of soda and z is the consumption of pizza. The consumer has 2000 Euros while the price of mineral water is 15, the price of soda is 55 and the price of pizza is 30 Euros. How much/many soda does the consumer buy?
A consumer buys Bread (B) and Milk (M) each week at prices of Rs. 10 and Rs. 8 respectively. Suppose
that the consumer's current consumption of Bread and Milk is giving him MUBrend = 80 and MUMia = 70.
Is the consumer buying the utility-maximizing combination of bread and milk? If not, how should he
reallocate his expenditures between the two goods to maximize utility? Draw diagram and explain.
