A big key phrase here is that "the tutor must be seated to the right of Louise", so if T is the tutor and L is Louise, then you can only have LT and NOT TL So basically LT is one person since you can't a) separate the two AND b) you can't reorder it

There are 8 chairs in the front, but 2 are taken up and combined into one "chair" so to speak. So there are really 82+1 = 7 "chairs" in the front row.
