Part II: Sequences and Series in Context
4) Suppose you practice the piano for 45 min on the first day of the semester and increase your practice time by 15 min
each day. How much total time will you devote to practicing during the first 15 days of the semester?
5) There are 650,000 people in a city. Every 15 minutes, the local radio and television stations broadcast a tornado

the approaching tornado. How many people still have not heard the news after 1 hour? After 2 hours?
6) Beth is fascinated with sea shells and she collects them every day at the beach. She starts with 32 sea shells in her
