3. In the text box below, please write your answer to the following question: the electric washing Imachine was invented about 120 years ago. In less than 30 years, annual sales in the United States had grown to almost one million units per year. Why do you think that more and more individuals bought a washing machine? Please think this over and give ONE reason with a brief explanation of why more individuals might buy washing machines between 1900 and 1928? Hint: do NOT use marginal utility theory. Marginal Utility theory works best for explaining why each individual buys more and more of a product as the price goes down. In general, individuals only buy one washing machine. So the question is why MORE individuals were buying electric washing machines. HTML Editora
