Palmona co. establishes a $250 petty cash fund on january 1. on january 8, the fund shows $165 in cash along with receipts for the following expenditures: postage, $36; transportation-in, $11; delivery expenses, $13; and miscellaneous expenses, $25. palmona uses the perpetual system in accounting for merchandise inventory. prepare journal entries to (1) establish the fund on january 1, (2) reimburse it on january 8, and (3) both reimburse the fund and increase it to $300 on january 8, assuming no entry in part 2. (hint: make two separate entries for part 3.)

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.
