What is the demand for goods L and Y given the utility function U(L,Y) = L+2Y where the price of L is $1 dollar per unit and the price of y is $Z per unit.

Suppose that Sam has a utility function u(x, y)= x+y where x is the amount of good 1 and y is the amount of good 2. The price of good 2 is $20, and the income is $ 90. With the $5 price decrease of good 1 from $10 to $5, then what is the substitution effect and income effect on the demand for good 1?

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

Bob has utility function U(x,y)=x2+y over goods x and y a) Do we have a name for this type of utility function? Are Bob's preferences well-behaved? b) Let Bob have budget I=$60, and let prices be Px=$30, Py=$10. Find Bob's optimal basket of goods x and y. Is this an interior or corner solution? c) What will happen if the price of good y doubles? [Think about: can we use this utility function to describe preferences over pet snakes and pet mice?]

Suppose a consumer had a utility function given by: U=X + 4Y. If the price of Good X (Px) is $1 and the price of Good Y is $8 then what is the utility maximizing quantity of Good X the consumer will purchase with a budget of $4? (Round to the nearest two decimal places if necessary.)

What economic principle suggests that individuals will continue to consume more of a good or service until the marginal benefit equals the marginal cost? A) Law of Demand B) Law of Supply C) Law of Diminishing Marginal Utility D) Equilibrium Price
