Gateway Computers wants to extend credit to their customers. Management feels that extending credit will not only increase sales, but also give customers more opportunity to purchase higher-end computers. They would like to use an expert system to ensure consistent credit decisions. The chief financial officer of Gateway has decided to bear minimal risk, by extending credit to customers with a favorable credit history and an annual income of $85,000 or more. Those with unfavorable credit and an annual income of less than $85,000 are denied credit. Customers with favorable credit and less than $85,000 annual income are extended credit if they have a down payment of 20% or more, and denied credit if the down payment is less than %20. Customers with an unfavorable credit history are denied credit if their annual income is $85,000 or more and their employment history is less than 3 years. If these customers have been employed for 3 years or more, the decision to extend credit will depend on the down payment. If they can make a 20% or more down payment, their credit is approved. If not, it is denied. Develop an expert system or decision tree with B-wise for Gateway.
