Suppose there are 2 countries: the U.S. and China. The U.S has 50,000 labor hours available. It takes the U.S. 4 hours to make a cake and 16 hours to make a table. China has 110,000 labor hours available. It takes China 5 hours to make a cake and 50 hours to make a table.
Determine the maximum quantity of each good that the U.S. and China could produce.
a bicycle tire is filled with air to a pressure of 100 psi at a temperature of 100 degrees C. Riding the bike on asphalt on a hot day increases the temperature of the tire to 58 degrees C. the volume of the tire is increased by 4%. what is the new..
