The question is an expenditure minimization question. The answer should be very detailed and clear, THANK YOU!!!
If the utility function for a consumer is defined by U=6X^0.6Y^0.7 . Given that the consumer's income is 300 currency units and unit price of goods X and Y are 12 and 15 currency units respectively, calculate the equilibrium quantity of both goods. Compute the price elasticity of demand for both goods and interpret your results. If income and prices of the two goods increase by 50%, calculate the equilibrium quantities of both goods
Consider a person who consumes two goods, x and y, and has a utility function given by U(x, y) = In(x)+y. This person has an income of $100 and faces a price of $0.50 for good x and $1 for good y. Price of x then rises to $0.60. Solve for the compensating variation (CV) and equivalent variation (EV) of this price change. Show your work.
The total utility of your consumption of widgets is 43; it changes by 5 with each change in widgets consumed. The total utility of your consumption of wadgets is 56 and changes by 5 with each change in wadgets consumed. The price of widgets is $5 and the price of wadgets is $5.Should you change your consumption pattern? Yes, you should consume both more widgets and more wadgets. No, you should continue your present pattern of consumption. Yes, you should consume more widgets and fewer wadgets. Yes, you should consume fewer widgets and more wadgets.

please explain the marginal utility and when exactly to use it ?
please answer asap with steps
4.13 CES indirect utility and expenditure functions In this problem, we will use a more standard form of the CES utility function to derive indirect utility and expenditure functions. Suppose utility is given by U(x, y) = (x° +y®)'/8 [in this function the elasticity of substitution o = 1/(1 – 6)]. a. Show that the indirect utility function for the utility function just given is V = I(p, + p,)¬/", where r = 8/(ò – 1) = 1 – 0. b. Show that the function derived in part (a) is homogeneous of degree zero in prices and income. c. Show that this function is strictly increasing in income. d. Show that this function is strictly decreasing in any price. e. Show that the expenditure function for this case of CES utility is given by E = V(p', + p,)''". f. Show that the function derived in part (e) is homogeneous of degree one in the goods' prices. g. Show that this expenditure function is increasing in each of the prices. h. Show that the function is concave in each price.

Steve spends all his income on meals at restaurants and paperback novels. His usual restaurant meal costs $20, and paperback books cost $10. When Steve’s monthly income is $250, he goes out to eat 10 times and purchases 5 books. When his income rises to $280, he goes out to eat 8 times and purchases 12 books. Determine whether the following statements are true or false: Paperback books are normal goods Restaurant meals are necessity goods Paperback books are luxury goods
Question 4 Naomi's expenditure function defined for a month for two commodities, Cassava (Q₁) and Banana (Q₂) is given by: 1. 11. Where P₁ is the price of Cassava (P₁>0), P2 is the price of banana (P₂ >0) and U is the fixed utility. The income of Naomi is m, where m > 0. Derive the indirect utility function for Naomi (Hint: Use the duality conditions) Using the Shephard's Lemma condition, derive Naomi's Hicksian demand function for Cassava (Q₁). iii. H IV. [125P,PU3 8 Using the Roy's identity, derive Naomi's Marshallian demand function for Banana (Q₂). Using the answer in (i), evaluate Naomi's maximum utility level when the price per tuber of Cassava is 5 cedis, the price per finger of banana is 10 cedis and her income is 250 cedis.
PROBLEM 3 – Slutsky Equation, Income Effect, Substitution Effect, and Total Effect There are two goods which quantities are to be denoted by x and y, while prices are denoted by px and py, respectively. There is a consumer whose income is to be denoted by I and utility by u. His expenditure function is known to be: *see image* Using slutsky equation, decompose the effect of an infinitesimal increase in Px on demand of good x.
