A primitive economy depends on two basic goods, yams and pork. Production of 1 bushel of yams requires 1/8 bushel of yams and 1/2 of a pig. To produce 1 pig requires 1/6 bushel of yams. Find the amount of each commodity that should be produced to get the following. (a) 1 bushel of yams and 1 pig (b) 300 bushels of yams and 70 pigs _ (a) Find the input-output matrix, A, and the demand matrix, D, for this economy. The input-output matrix is |:| (Type an integer or fraction for each matrix element.)
