A medium-sized enterprise plans to develop a software system to support project selection over the next 10 years. The cost conditions to be encountered during their lifetime are classified as development, programming, operation and support for each project. Three systems have been proposed, A (custom), B (adapted), and C (current). The costs are as in the table below. Knowing that the quarterly interest rate is 2.18%, choose the best alternative using present value analysis.
