Violet looked through a catalog and found a dress. She wanted to order. she used a calculator to determine that the total cost of the dress, tax, and shipping was $129.207. What is the total rounded to the nearest penny?

So,

Before I do anything, I would like to ask the question that should subconsciously and instantaneously pop into everyone's heads: Why is Violet calculating mills? Where does she live? Either it is a place where the value of money is very high, or Violet is very poor, so mills factor into prices.

To round $129.207 to the nearest cent (penny), find the mill's place, which is the 7.

Since 7 is greater than or equal to 5, round up.

$129.207 - - > $129.21

Violet's dress will cost $129.21 rounded to the nearest cent.
