The Steal-a-Deal gift shop specializes in heavily discounted merchandise for the holiday season. The store prices are so appealing that lines of people queue up in the early AM hours in front of the store doors in order to secure a place in the line. On the morning after Christmas, one of the busiest days of the year, the store opened its doors at 8:00 AM. At that time there were 120 customers already waiting in line. The customers leave the line at the rate of 4 per minute. From 8:00AM to 10:00AM, new customers arrive at the rate of 2 per minute. I How many people are waiting in line at 9AM? In the Steal-a-Deal gift shop, suppose that there are 175 customers waiting in line at noon, and Jacob arrives at the store at that time. How long should he expect to wait, in minutes?
