Query d):

Select Upper(publisher), title,'Selling_price' || ' ' ||'$' || price as Selling_price from book where price between 3 and 6;


Query e):

select book_copies.branch_id, book.title, book_copies.no_of_copies from book

inner join book_copies on book.book_id = book_copies.book_id

inner join library_branch on library_branch.branch_id = book_copies.branch_id where library_branch.branch_name = 'Newport Branch' and book.title = 'The Lost Tribe';
