Egg Laying

The following is a new variation of an old friend.

Though it looks rather complicated and difficult, it is absurdly easy if properly attacked.

If a hen and a half lays an egg and a half in a day and a half,

how many and a half who lay better by half will lay half a score and a half in a week and a half?
