Consider the following account balances of the sour cream law firm at the end of the year: accounts payable $4,400 salaries expense 12,800 cash 1,700 common stock 2,400 service revenue 8,300 supplies 4,300 retained earnings 1,100 utilities expense 5,000 how many of these accounts would appear in sour cream's year-end income statement?

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.
