Twyla Enterprises uses a computer for sales invoices: Retain or Replace the machine

Twyla Enterprises uses a word processing computer to handle its sales invoices. Lately, business has been so good that it takes an extra 3 hours per night, plus every third Saturday, to keep up with the volume of sales invoices. Management is considering updating its computer with a faster model that would eliminate all of the overtime processing.
