Chuck, a single taxpayer, earns $80,750 in taxable income and $30,750 in interest from an investment in city of heflin bonds. (use the u. s. tax rate schedule.) (do not round intermediate calculations. round your answers to 2 decimal places.)

In order to be thoughtful about the implementation of security policies and controls, leaders must balance the need to reduce with the impact to the business operations. doing so could mean phasing security controls in over time or be as simple as aligning security implementation with the business’s training events.

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.
