A private airplane can cost as little as 3-4,000 for a used Cessna right up to 4-5 million for an executive jet.
Jet propulsion improved airplane flights. Before that piston engines were used. They were much slower compared to the jet engine.
Fueling a jet is so much money.
It depends on what kind of jet or commercial airplane it is.
About 100,000,000
A jet IS an airplane. However most piston engined aircraft fly in the speed range of 150 -350 mph, while most civilian jets fly between 400 and 600 mph. Military jet fighters are much faster.
New Flight Charters offers private jet charter rentals that range in price from $1050/hr for an Executive Turboprop Airplane, to $7600/hr for a Large Cabin Jet. Another option is that you can rent a non stop jet from New York to Los Angeles for $22,900 total cost.
The first jet airplane was designed in Germany in the early 1940's.

Way too much.
Boeing made the first JET airplane with its Boeing 707, or Dash 80 as it was called before.
