Comparing the total cost of watching a movie at the multiplex and a movie on DVD.
Suppose your friend likes movies. She watches some movies on DVD, which she likes, but she prefers to see movies at the multiplex; in fact, she likes seeing movies at the multiplex twice as much as she likes watching movies on DVD.
