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.

Suppose a movie theater determines it can charge different prices to patrons who go to weekday matinees and people who attend evening and weekend shows . the movie theater's goal is to increase total revenue. the price elasticity of demand for weekend and evening patrons is -0.40, and the price elasticity of demand for matinee moviegoers is -1.90. based on the price elasticity of demand for each group of people, how should the movie theater adjust its prices?
