In 1955 each farm worker in the United States produced enough food to feed 20 people. By 1960 farming methods had improved, and one worker could supply 25 people. By 1965 that number became 40 people. In 1970 it was 45 people.In 1975 it increased to 60 people. In 1980 one farm worker could suppy 75 people.
How many people do you think were supplied by one farmer in 1990?
