Use the relational schema of the Pine Valley Furniture (PVF) database to create and execute SQL queries. Here is the relational schema:

pvf_cust (cid, name, address, city, state, zipcode)

pvf_order (oid, orderdate, cid)

cid is a foreign key references cust(cid)

puf_product (pid, prod_desc, prod_finish, price, prod_line_ id)

puf_order_item (oid, pid, quantity)

oid is a foreign key references pvf_order(oid)

pid is a foreign key references pf_prod(pid)

Calculate the average price of all products. Round the price to 2 decimal places.
