Problem 2: Using four quarks (u, d, s, and c), construct a table of all the possible meson species. How many combinations carry a charm of 0 ? How many carry charm +1, and -1?

Find the values of x1 and x2 where the following two constraints intersect. (Round your answers to 3 decimal places.)   (1) 10x1 + 5x2 ≥ 50 (2) 1x1 + 2x2 ≥ 12

2. Alex and Bill share a flat. Alex enjoys reading in silence, while Bill enjoys listening to loud music. Bill controls his music system, which can produce noise levels up to 100 Decibels. Bill has no cash but Alex has £100. Their utility functions are given by: UA = 10(100 – D)i + (100 – M), %3D Ug = 10(D)i + M, where D denotes the Decibel level chosen by Bill, and M denotes any cash given to Bill by Alex. (a) Explain how Bill's music level affects Alex. Find the contract curve between Alex and Bill. Why is there a unique Pareto efficient noise level? (b) What is the maximum amount Alex would be willing to pay Bill to turn down the music to the Pareto efficient level? What is the minimum amount Bill would be willing to accept in order to turn down the music to the Pareto efficient level? Can the Pareto efficient noise level be achieved through private bargaining?
