Suppose the demand and Total Cost for a monopolist’s product is given by P = 100 – 7Q; TC = 20 + 20Q + 2Q2 a. Find the monopolist’s profit maximizing P and Q, and profit. b. Show that the second order condition is satisfied. Show that at equilibrium the slope of the MR curve is less than the slope of the MC curve c. Compute the elasticity of demand at the equilibrium. Briefly explain why demand is elastic? d. Compute the Revenue maximizing Q. What is the P at this Quantity? e. What is the elasticity of demand? Briefly explain why?

Asmartphone manufacturing company uses social media to achieve different business objectives. match each social media activity of the company to the objective it the company achieve.

Which of the following has the largest impact on opportunity cost

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.
