\The southeast division of a distribution company is planning on purchasing a new delivery truck for $18,500. The current truck has a book value of $5,000 and will be sold immediately. The new truck is expected to increase operating income by $6,000. Additional information is as follows: Current operating assets $800,000 Current operating income $82,500 Minimum rate of return 10% Profit margin 15% Based on the expected change in the return on investment metric, should the truck be purchased? Group of answer choices

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.
