Infоrmаtiоn fоr questions 21-25 The figure below depicts the production possibilities curve (PPC) for the U.S. аnd Cаnada, two countries that can produce cars and trucks. Assume the two countries trade only with each other. The U.S. and Canada have the same total amount of hours of labor engaged in production. Suppose that a U.S. worker needs 5 hours of labor to produce either a car or a truck. Calculate the total number of hours of labor available in the U.S., that is, the total labor force (in hours of labor) of the U.S. (Hint: if you need 5 hours of labor to make one car, how many hours of labor do you need to make 1000?) Enter a whole or decimal number, as appropriate. Enter 0 if the answer cannot be obtained with the information given. Only exact answer accepted.
