In this question we can see that most of the required information's are already provided. These information's are enough to find the necessary answer to the question. Alistair sells each book at a rate of 7.60 pounds and then there is also a VAT of 1/2% . Now first we need to find the rate at which Alistair is selling 1 book.
Amount of VAT for 1 book = 7.60 * (0.5/100) pounds
                                         = 0.038 pounds
Then by selling 1 book, Alistair receives = (7.60 + 0.038) pounds
                                                                = 7.638
Now by selling 1650 books, Alistair receives = (1650 * 7.638) pounds
                                                                       = 12602.7 pounds
So Alistair receives 12602.7 pounds after selling 1650 books.
