Suppose that a worker in caninia can produce either 2 blankets or 8 meals per day, and a worker in felinia can produce either 5 blankets or 1 meal per day. each nation has 10 workers. for many years, the two countries traded, each completely specializing according to their respective comparative advantages. now war has broken out between them and all trade has stopped. without trade, caninia produces and consumes 10 blankets and 40 meals per day and felinia produces and consumes 25 blankets and 5 meals per day. the war has caused the combined daily output of the two countries to decline by

Amathematical approximation called the rule of 70 tells us that the number of years that it will take something that is growing to double in size is approximately equal to the number 70 divided by its percentage rate of growth. thus, if mexico's real gdp per person is growing at 7 percent per year, it will take about 10 years(=70/7) to double. apply the rule of 70 to solve the following problem. real gdp per person in mexico in 2005 was about $11,000 per person, while it was about $44,000 per person in the u. s. if real gdp per person in mexico grows at the rate of 5 percent per year: how long will it take mexico's real gdp per person to reach the level that the united states was at in 2005? (hint: how many times would mexico's 2005 real gdp per person have to double to reach the u. s.'s 2005 real gdp per person?
