Need an opinion. This question says "a pair of trousers" doesn't this equate to 8 trousers?
If so then shouldn't we do 8x(29.99-23.99)= £48?
Its just a phrase.
We call trousers a "pair of trousers" coz they have two legs or smthn. But really a pair of trousers means 1 trouser.
(I think it's a British phrase, even saying 1 trouser just feels unnatural)
