You are given the following Classical-type table howing the number of days of labor input required to obtain 1 unit of output of each of the five commodities in each of the two countries:

(a) Assume that the wage rate in the United Kingdom (WUK) is £8/day, the wage rate in the United States (WUS) is $20/day, and the exchange rate (e) is $2/£1. With this information, determine the goods that will be U.K. exports and the goods that will be U.S. exports.
(b) Keeping WUS at $20/day and keeping the exchange rate at $2/£1, calculate the upper and lower limits (in pounds per day) to the U.K. wage rate that are consistent with two-way trade between the countries.
(c) With WUK at £8/day and WUS at $20/day, calculate the upper and lower limits (in $/£) to the exchange rate that are consistent with two-way trade between the countries.
