PLEASE HELP ME SIMIPLFY THE DECISION TABLE BELOW IF POSSIBLE!!

The owner and store manager have decided to offer customers a service plan were they pay a flat rate once a year. With this plan, customers only pay for the cost of parts when they have their appliance(s) serviced. They can only buy a service plan if they have purchased an appliance from Appliance Warehouse. With this new service plan, if they have service on their appliance more than 3 times during the year, they will have to pay the full amount of the service fee and cost of parts. If the customer does not buy a service plan but buys their appliance from us, we will give a 20% discount off the service fee for the life of their appliance. Everyone else will pay the full cost of the service plan and parts cost. create a decision table and tree from these rules.
