I want to know the answer to the following question:
How much extra money from DST did Fortune predict for 7-Eleven on account of DST?
All the background I'm provided with is that "In 1984, Fortune magazine estimated that a seven-week extension of DST would yield an additional $30 million for 7-Eleven stores, and the National Golf Foundation estimated the extension would increase golf industry revenues $200 million to $300 million.". Is that enough to answer the question?
