A group of workers was supposed to make 768 vacuum cleaners in a certain amount of time. For the first five days, the team made exactly the number of vacuum cleaners they were supposed to make in order to be finished by their deadline. For the rest of the time they made 6 more vacuum cleaners each day than they were supposed to and so the day before the deadline they already had 844 vacuum cleaners. How many vacuum cleaners was the group supposed to make each day?
