Napoleon Bonaparte, as Emperor of France, was at war with England. Louisiana wasn't doing him any good (since the British Royal Navy would cut off any trade with France) and he needed the money to finance the war. The United States bought the Louisiana Territory in 1803, doubling the size of the United States. The money didn't do him much good, as the French Navy was slaughtered by the Royal Navy at the Battle of Trafalgar in 1805.
No. The United States purchased the Louisiana Territory from France. Spain once owned Louisiana as a result of the Treaty of Paris in 1763. But, the French got it back with a secret treaty in 1800. Presient Jefferson used the Louisiana Purchase as a result, gaining much land.
About $15 million dollars for the whole Louisiana Territory
France was desperate for money, so they sold the land to Jefferson for $15 million (a cheap price for that much land!). Seeing a great deal and a good chance to expand the U.S., Jefferson bought it.
Much of the money had to be borrowed from European bankers ,and that fact was indeed a problem in getting the Senate to ratify the deal.

The Louisiana Purchase occurred during Thomas Jefferson's term as the United States president. Land had been bought by the United States from France. However, the United States did not know how much land it had bought. Jefferson sent an expedition to map the new territory. This was known as the Lewis and Clark expedition.
Oregon was not bought.
