The person surveyed went to a major sporting event
The point (1,1400) means that the person spent 1 day on vacation and spent $1400. Since $1400 is above the average (the line), the person went on an expensive vacation. This can rule out staying home and going on a day trip. However, the person only spent 1 day on vacation, which rules out going on a cruise. The only answer left with is going to a major sporting event, an expensive, single day vacation.
