Refer to Exhibit 34-9. In the no specialization-no trade case, suppose country X produces and consumes 100 units of good A and 20 units of good B. Country Y produces and consumes 20 units of good A and 60 units of good B. If the two countries specialize and trade, and the actual amounts traded are 125 units of good A for 25 units of good B, how many more units of good B will country Y consume by specializing and trading?
