Exercises Linear equations for the consumption and saving schedule take the general form C=a + bY and S=-a+(1-b)Y, where C, S and Y are consumption, saving and national income respectively. (1) Use the given data to develop specific numerical values for the consumption and saving equations. Write the using these values

1. Summary: （全文） One of Hemingway's war and love stories, this novel takes place in Italy during World War I and is tied closely to the author's own experience as an American Ambulance Driver for the Italian Army.

Five Famous Symbols of American Culture The Statue of Liberty In the mid-1870s, French artist Frederic Auguste Bartholdi was working on an enormous project called Liberty Enlightening the World, a monument celebrating US independence and the France-America alliance. At the same time, he was in love with a woman whom he had met in Canada. His mother could not approve of her son’s affection for a woman she had never met
