Whenever you see the $ symbol in front of a number, you should use the word “dollar” after the symbol. Like any regular count nouns, you have to add an –s to indicate the amount is more than 1.
- $50 – fifty dollars.
- $1 – one dollar
When cents are involved, use the dollar amount to determine if the dollar is plural.
- $50.50 – fifty dollars and fifty cents
- $1.50 – one dollar and fifty cents (or, more commonly, a dollar fifty)
