Solve the problem.The average waiting time in a line before getting served is given by ?W = 
where A is the average rate that people arrive at the line and S is the average service time. At a certain bank, the average service time is 4 minutes. By sketching a graph of the equation on the interval 
answer the following questions. What happens to W when A is close to zero? Why does this make sense? What feature of your graph gives this information?
What will be an ideal response?
Answers will vary. Possible answer: As A approaches zero, the waiting time, W, becomes infinitely large. This information is given by the vertical asymptote, 
This makes sense because as the time between arrivals of customers gets smaller, the waiting time increases, becoming infinitely large for
