If one was to keep careful track of how much housework Willy and Sally actually did around the house each week, something Sally would, of course, never, ever do, one would find that last year the two of them together typically did 30 hours of housework a week. And if one was to carefully examine things this year, one would discover that Willy was doing 3 hours less a week while Sally was doing 20% more than she had been doing last year and that together they now typically did 31 hours a week. How many hours a week does each do now?
