A firm is looking to lease improved high-speed data transmission lines between two remote locations from a service provider. Currently they transfer files with an average size of 100MB (megabytes) on a T1 line rated at 1.5 Mbps (megabytes per second) and it takes 9.4 minutes to transfer this file. It is estimated that in an 8-hour day, this data transfer happens 2 times per day each for 20 employees in a certain group and that each employee makes (including...
