A group of workers had agreed on a very strange payment schedule. Each of
them would get $100 for every day that they had worked, but for every day they
did not work will have to return $25. After 30 days they realised they did not
earn any money. How many days the workers did not work? Choose the correct choice from the following answers:  A) 15  B) 24  C) 30  D) 20  E) 10
