- - - - in other words, the opportunity cost of a book, is 1/2 a movie
        
        since you are essentially saying the same thing (the marginal cost/the cost of an additional unit; the opportunity cost/what you are losing from making a choice....), opportunity cost = marginal cost
- - - - maybe because tesla cars are more expensive to fix than gas cars
      - ppl are more familiar with driving a gas car than an electric car
        
        consumer demand
        
        ...has gone down
      - price of tesla cars have gone down over the years, DRASTICALLY

    - - so the opportunity cost of a movie would be: -2
      - opportunity of a cost of a movie, relative to the cost of a book
        
        essentially, you'd be asking: "how many books would you have to give up to get an additional movie
