1. Sid bought a new $1,500,000 seven-year class asset on August 2, 2020. On December 2, 2020, he purchased $900,000 of used five-year class assets. If Sid elects Sec. 179 and does not take additional first-year depreciation, what is the maximum cost recovery deduction for these purchases for 2020

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.
