Suppose you paid $300 to take an economics course, which meets 30 times for one hour a class, during the course of the semester. instead of attending class, you could have either flipped hamburgers for $8 an hour or waited tables for $5 an hour. given this information, the opportunity cost of attending each class session is: a. $30.b. $8.c. $5.d. $13.

David consumes two things: gasoline (g) and bread (b). david's utility function is u(g, b) = 10g^0.25 b^0.75. use the lagrange technique to solve for david's optimal choices of gasoline and bread as a function of the price of gasoline, p_g, the price of bread, p_b, and his income m. with recent decrease in the price of gasoline (maybe due to external shock such as shale gas production) does david increase his consumption of gasoline? for david, how does partial differential g/partial differential p_g depend on his income m? that is, how does david's change in gasoline consumption due to an increase in the price of gasoline depend on his income level? to answer these questions, find the cross-partial derivative, |partial differential^2 g/partial differential m partial differential p_g.
