The Tru-Green Lawn Company provides yard care services for customers throughout the Denver area.
The company owner recently tracked the time his field employees spent at a sample of customer locations.
He was hoping to use these data to help him with his scheduling and to establish billing rates. The following sample data, in minutes, were recorded:
