Giana is the executive secretary to the ceo of a large public corporation. one day her boss takes her into a back room containing numerous cardboard file boxes and three shredding machines, and he tells her to shred every document and file in the room. he then says, "we're under investigation by the sec, and if they get their hands on anything in this room, we're ruined." she asks what is going on and is told that the company has been perpetrating fraud for years and needs to destroy all the evidence. if giana then agrees to shred the documents and files, what, if anything, could happen to giana?

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.
