Elizabeth has one dollar and six pennies. How many cents does she have? And which of these is the correct way to write the amount of money she has?

Let’s start here: how many cents does she have? How many cents is one dollar and six pennies equal to? One dollar is equal to 100 cents. Six pennies is equal to six cents. 100 plus six equals 106 cents. Elizabeth has 106 cents.

The second part of our question wants to know what is the correct way to write the amount of money she has. If we look at the first option, it has a dollar symbol and then the number 106. This means 106 dollars. Elizabeth does not have 106 dollars.

Our second option has a dollar symbol and a decimal. But it’s missing a hundreds place. Because when we talk about dollars and cents, cents is measured in hundreds. We always need two values after the decimal place. This dollar sign with the 1.6 is not a correct way to write about money.

So we come to the last option. With the dollar sign, it says one dollar and six cents. One dollar and six pennies would be written with the dollar sign a one, a decimal, and then a zero six to represent the six pennies — the six cents.

Elizabeth’s 106 cents would be written as one dollar and six cents.
