Okay i stuck on a problem can anyone help?

There are 14 people total.7 are girls a day.Everyone has to work for 7 days also everyone has to have 2 days off.So how many days does a girl work a week?

When you say "everyone has to work 7 days", over what period of time does that apply?

What do you mean by "7 are girls a day"? What are they thre rest of the time?
