Polk Co. acquires a forklift from Quest Co. for $30,000. The terms require Polk to pay $3,000 down and finance the remaining $27,000. On March 1, year 1, Polk pays the $3,000 down and accepted delivery of the forklift. Polk signed a note that requires Polk to pay principal payments of $1,000 per month for 27 months beginning July 1, year 1. What amount should Polk report as an investing activity in the statement of cash flows for the year ended December 31, year 1?

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.
