A Tupperware party host was frustrated at her attempts to get more people to host sales parties for her. She finally offered to pay $25 to any host who (a) hosted a party for her and (b) arranged for 2 other friends to host parties (during next month). To her surprise, it worked. She started with 5 hosts in the first month. If this continues for the entire year. How many parties will there be during the year?
