Antonia Clark, the Senior Marketing Manager of Tough Mudder, talks about how operations teams, creative teams, and merchandising teams have to work collaboratively to put on events.
If she assembled specific members from each of these units to work together in a team to set goals and pursue their own goals in ways defined by the team itself, then this would be an example of what concept?

a. Functional Team
b. Virtual Team
c. Affinity Group
d. Venture Team

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.
