* Four hundred fifty dollars (This is the most common and formal way)
* $450 (This is the most concise way)
* Four hundred and fifty dollars (This is also acceptable, but less common)
You can also spell it out in numerals and include the currency symbol:
* $450
The best way to spell it depends on the situation. For example, in a formal document, you would likely use "four hundred fifty dollars." In a casual conversation, you might just say "$450."
