How can you get from Miami airport to the city?

I want to know how can you get from Miami airport to the city? And if you can give me an answer in respect to the price I would be grateful. I dont care if it takes me twice as much time then usual I am just interested in spending as little money as I have to. Every option comes in consideration, except of me walking from Miami airport to the city.

The easiest way is to take a cab. And I think it will not cost more then $20 or so. But I think the cheapest way is to take public transportation. I dont know how much the ticket costs, but I am sure it is cheaper then the cab. When I think a bit more about your question I know that the cheapest way is to hitch hike to the city. That is not like you will have to walk to the city and you wont have to pay nothing. The only downside to this means of transportation is that you will have to talk a little if your driver likes to make small talks.
