Scarlett, Anthony, and Madison collect coins. The given bar graph shows how many coins each of them has. How many more coins does Anthony have than Scarlett?

First, let’s examine our bar graph. The numbers on the left line tell us the number of coins each collector has. And the labels on the bottom tell us which line belongs to which collector. Our question is interested in comparing Anthony and Scarlett. First, we find their two lines. And then we find out how many coins Anthony has.

The top of Anthony’s line ends at the number nine. Anthony has nine coins. Next, we want to know how many coins Scarlett has. The top of her line ends at the number six. Scarlett has six coins. To find out how many more coins Anthony had than Scarlett, we need to use subtraction. We need to subtract Scarlett’s six coins from Anthony’s nine coins. Nine minus six is three. Anthony had three more coins than Scarlett.
