2. The prices, in dollars per unit, of the three commodities X, Y and Z are x, y and z, respectively Person A purchases 4 units of Z and sells 3 units of X and 3 units of Y. Person B purchases 3 units of Y and sells 2 units of X and 1 unit of Z. Person purchases 1 unit of X and sells 4 units of Y and 6 units of Z.
