In the U.S., it is written $24.50, and you say, " twenty-four dollars and fifty cents." (Some people leave out the word "and," but this sounds a bit more formal). In informal conversation, people usually say "twenty-four fifty." Twenty-four dollars and five cents is written $24.05. You say, "twenty-four dollars and five cents" (you can also leave out "and" ). In informal conversation, you will often hear, " twenty-four oh five (the zero is pronounced like the letter "o")

The correct way is: "Twenty-four dollars, fifty cents." We do have colloquial ways of putting this, such as "twenty-four, fifty", but they would not be written this way, only spoken this way. If there is an actual *coin* in the amount, sometimes people will colloquially use the coin to add on to the dollar. Like this: $24.05 would sound like "Twenty-four and a nickel." $24.25 would sound like "Twenty-four and a quarter." (Oddly enough, I rarely hear this used if there is a dime involved. It's usually just "twenty-four-ten" or "twenty-four dollars, ten cents".) If there is an amount in cents that is under ten cents, we sometimes will colloquially use the letter "O" in front of it. Like this: $24.05 will sound like "Twenty-four o-five." $24.08 will sound like "Twenty-four o-eight" However, Pouyan's suggestion to use "Twenty-four-five" applies when you are talking about money over one thousand. For example: $24,500 is often heard colloquially as "Twenty-four, five". If you ever visit a car dealership or listen to car advertisements on the radio or TV, it's a shortened way to say the price so it doesn't sound so intimidatingly high. Example: "Check out our brand new Ford starting at twenty-four, five." (Of course we know that it means 24 *thousand* as there wouldn't be any such thing as a car going for $24.05.) ↑ Things change when you get into the millions. $24,500,000 can be spoken as "twenty-four POINT five million". This is slang, and native/fluent speakers understand that it doesn't literally mean 24,000,000.5 -- but the "point-five" or halfway mark of million is "point-five". I hope this helps! :)
