When Johnson and Johnson removed all Tylenol from the stores after some containers were tampered with leading to the poisoning and killing 7 people, the company was: a) accepting the fact that consumers would never use Tylenol again.
b) designing promotional discounts to sell the returned Tylenol in less developed countries.
c) being directed to do so by the Food and Drug Administration.
d) sacrificing short-term profits for long-term credibility.
e) acting unethically.

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.
