On January 1, 2021, G Corporation agreed to grant all its employees two weeks paid vacation each year, with the stipulation that vacations earned each year can be taken the following year. For the year ended December 31, 2021, G's employees each earned an average of $830 per week. A total of 570 vacation weeks earned in 2021 were not taken during 2021. Wage rates for employees rose by an average of 6 percent by the time vacations actually were taken in 2022. What is the amount of G's 2022 salaries expense related to 2021 vacation time

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.
