- Lan's utility function is U (x,y) =6.9 x².9y7.4. If the price of good X is 8.3 and Lan's optimal bundle has x*-9 units of good X and y*=1.1 units of good Y, what is the price of good Y?arrow_forwardMary has the following utility function: u(x, y) = 3 ln(x) + 2y. Her income is given by I = 10 and the prices originally are p = 1 and py = 2 (b) How much of each good is Mary currently consuming?arrow_forwardXander has a utility function u(x,y) = xy and an income of M. Assume that the price of x is $4 and the price y is $2. If Xander's income rises from M = 104 to M = 152, what the resulting increase in demand for good x? increases by 6 units increases by 9 units increases by 11 units increases by 14.5 unitsarrow_forward
- 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?arrow_forwardIf 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 goodsarrow_forwardBob 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?]arrow_forward
- 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.)arrow_forwardWhat 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 Pricearrow_forward
