If a consumer is consuming two commodities X and Y and his utility function U (X,Y)=2XY+6.if the price of the two commodity are 2 and 6 respectively, and the consumer has a total income of 80 birr to be spent on the two goods, a)find the utility maximizing Quantity of good X and Y. b) find the MRSxy at equilibrium. c) find the MRSyx at equilibrium.
Consider a market where supply and demand are given by Qx s = -16+Px and Qd=92-2Px suppose the gouvernment imposes a price floor of $40, and agrees to purchase any and all units consumers do not buy at the floor price of $40 per unit. determine the cost to the gouvernment of buying firm's unsold units. Compoute the lost social welfare (deadweight loss) that stems from the $40 price floor

A 70 lb bag of rice is being pulled by a person by applying a force F at an angle θ as shown. The force required to drag the bag is given by: F(θ)=70μ/μsinθ+cosθ where μ=0.35 is the friction coefficient. (a) Determine F(θ) for θ= 5°, 10°, 15°, 20°, 25°, 30°, 35° (b) Determine the angle θ where F is minimum. Do it by creating a vector θ with elements ranging from 5°to 35°and spacing of 0.01. CalculateF for each value of θ and then find the maximum F and associated θ with MATLAB's built-in function max
