To welcome the Beijing Olympics, Aunt Li started to make a batch of large colored flowers for the Olympic Exhibition Hall. On the first day, she made 1/8 of the total number, and on the second day, she made twice as much as the first day. If we do 251 more flowers, it will be just half of the total number. How many flowers are there in this batch?
