Question

When the two countries did not specialize, the total production of jeans was 18 million pairs per month, and the total production of corn was 52 million bushels per month. Because of specialization, the total production of jeans has increased by
6
million pairs per month, and the total production of corn has increased by
4
million bushels per month.

Answer 1

When the two countries did not specialize, the total production of jeans was 18 million pairs per month, and the total production of corn was 52 million bushels per month. Because of specialization, the total production of jeans has increased by 6 million pairs per month, and the total production of corn has increased by 4 million bushels per month, so the total production of jeans is 18 + 6 = 24 million pairs per month, and the total production of corn is 52 + 4 = 56 million bushels per month.
