This is software testing question is decision table;

Consider a credit card problem. If you are a new customer and you want to open a credit card account
then you will get a 15% discount on all your purchases today, second if you are an existing customer and
you hold a loyalty card, you get a 10% discount and third if you have a coupon, you can get 20% off today

Make a decision table for the above given scenario. Reduce it if possible
