Discrete Math: (Need help with a-h)

1.Let P(x) be the open statement "x is thick", Q(x) be "x has a hard cover", R(x,y) "x is more expensive than y", S(x,y) "x is harder to read than y", and let B be the set of all books. Write the following statements in terms of quantified symbolic logic.

(a) Some books have hard covers.

(b)No books are thick.

(c) Any thick book has a hard cover.

(d)There is a book that is harder to read than any other.

(e) Some books are more expensive than others.

(f)Books with hard covers are more expensive than books without hard covers.

(g) Books that are harder to read are more expensive.

(h)Any book more expensive than a thick book is also harder to read (than that thick book).
