Final answer:
A person would typically pay a monthly fee for a medical discount plan, which offers reduced costs for various medical services. Medicare, particularly Medicare Part B, is the public healthcare system that provides this type of coverage to individuals over sixty-five years old.
Step-by-step explanation:
With a medical discount plan, a person would generally pay a fee to get discounts on specific services. Typically, such fees are paid on a monthly basis. This can include discounts on physician services, medical tests, and outpatient visits. As for the public healthcare system that offers insurance primarily to people over sixty-five years old, this would be Medicare. Specifically, Medicare Part B is an optional insurance system covering health-care costs outside of hospital stays and includes various services for which the participants pay monthly fees, deductible charges, and copayments, with a significant portion of the overall costs being subsidized by the government.
