An engineering firm has hired a Human Resources consultant to see how they can optimize the hourly productivity of its engineers. It is found through 'experiment' that in a large shared office the productive hours H that n number of engineers work each day, can be modelled by n + 130 What is the optimal number of engineers the firm should allocate to one of its large offices to ensure maximum hourly productivity? 3 marks]
