The truck, or the trailer? For a new power unit, expect to pay, at a minimum, $120,000 at least.
This varies greatly depending on the type of truck. For example, a sleeper tractor weighs more than a day cab, a refrigerated van trailer weighs significantly more than a flatbed trailer, and so on. I drive a tandem axle day cab Sterling semi (this is a semi tractor with a total of 3 axles and no sleeper), and I pull a 53-foot dry van trailer (this is a box trailer without a refrigeration unit). When I have run it across a scale empty with about 120 gallons of fuel (this will also change weight as fuel weighs about 12 pounds per gallon), the whole truck weighs very close to 29,600 pounds. An empty semi can weigh as much as about 40,000 pounds, leaving room for 40,000 more of cargo before reaching maximum legal weight of 80,000.
A semi trailer costs over $100,000.
ranges between 17k-20k
17,000 - 20,000 lbs.
Typically, between 16,000 and 18,000 lbs.

That depends on what type of trailer. They range from around $30,000 to over $100,000.
Most trailers are semi trailers. You're probably asking the difference between a semi trailer and a full trailer. A semi trailer is not wholly self supporting, and weight is distributed both the trailer axles, and to the tow vehicle. A full trailer supports its own weight fully.
You call it a semi because it pulls a semi trailer.A semi is a type of trailer. A semi-trailer, as opposed to a full trailer, means it only has axles at the rear of the trailer and a full trailer has axles at the front and rear of the trailer. We call these in the UK "drags", as in wagon and drag, where the wagon that pulls the drag can carry a load on its own, whereas the semi-trailer truck, or tractor unit cannot carry anything without a trailer.
Trailer is way more bigger than a semi-trailer. Common misconception between a trailer and a semi-trailer. Technically, a trailer has wheels in front and rear and is hitched to a pulling vehicle (car,truck,etc.) A semi- trailer only has wheels in the rear and is hitched to a pulling vehicle (car,truck,etc.)
A trailer with 10' California spread can have 40,000 on the trailer axles without requiring a permit.
