Agro Tech Corporation is considering investing in a new IT system for selling to its clients. The company has identified two new possible systems, which would be suitable for its customers. Only one of the systems can be selected and the directors are looking for guidance on which system would be the best. The company requires a 15% rate of retum on projects of this nature. The installation cost per project will be R100 000 each, while systems can be disposed for R200 000 each after five-years life span.
