Newspaper Machines and Soda Vending Machines Operate Very Differently

Essay

Newspaper machines and soda vending machines operate very differently. The newspaper machine is a mechanical box. You place your four quarters in the machine and you open the door and low and behold there is a stack of newspapers at your disposal. Most people take one and close the door for the next patron to purchase his own copy. But notice that soda vending machines don't operate the same way. They are also mechanical but when the four quarters are inserted and a selection is made only one can of soda is available for the consumer to purchase. Explain in terms of marginal utility why these two machines are designed so differently?
