Adelle loves to run and she needs new running shoes. She has the choice to either buy a new pair or take a pair that her friend is offering for free (her friend bought them but they don't fit well and have therefore not been worn). The shoes she is considering buying will cost $180, are super comfortable, and are a nice blue colour. The free pair is slightly less comfortable, and a weird orange colour. If she chooses to take the free pair her opportunity cost will equal the lost extra comfort of the blue shoes, plus the lost enjoyment of the nicer blue colour.
