Document Summary
Supplementary questions for hp chapter 6: solve the following matrix equation for a, b, c and d: (cid:20) a b. Consider a model in which only two commodities are related to each other. For i equal to 1 or 2, let: Qdi be the quantity demanded of the commodity i. Qsi be the quantity supplied of the commodity i. For simplicity, the demand and supply functions of both commodities are assumed to be linear. A is the coe cient matrix and x and b are column matrices): let a = . Find a65: (a) express the equations y1 = x1 x2 + x3 y2 = 3x1 + x2 4x3 y3 = 2x1 2x2 + 3x3 and. 1 z1 = 4y1 y2 + y3 z2 = 3y1 + 5y2 y3 in the matrix forms y = ax and z = by . Then use these to obtain a direct relationship. When fully occupied, the tables seat 108 customers.
