The cost of waiting is estimated to be about an average of $20
per hour. Each pump cost about $11000 per year for the maintenance
fee and investment loan interests. Assuming 365 days a year and 12
hours per day. Determine how many new pumps need to be installed to
minimize the expected total cost per hour. If no new pumps need to
be installed, answer 0. 60 customers per hour (mean arrival rate)
and 15 customers per hour (mean service rate)
