You are working for a member of congress. They have tasked you to come up with a methodology to determine how much Medicare for All/Universal healthcare would cost. Facts: 1. Medicare part A(Hospitalization) is free for anyone 65 and older, and their spouses, who has worked for 10 years 2. Medicare part B(doctors) costs on average $140/mo. 3. Medicare part D (drugs) costs on average $200/mo. 4. Medicare pays for 80% of allowed medical expenses. I do not want you to tell me how much it will cost to provide universal healthcare, I want you to show me how you will come up with that cost. Also, list what assumptions you need to make to come up with that cost.
