Answer 1

To represent Gabrielle's savings in the piggy bank over time, we can create a table based on the information provided.

Gabrielle starts with 6 dollars and adds 3 dollars each week. We can fill out the table for 0, 1, 2, and 3 weeks:

| Time in weeks | Dollars in the piggy bank | |---------------|----------------------------| | 0 | 6 | | 1 | 6 + 3(1) = 9 | | 2 | 6 + 3(2) = 12 | | 3 | 6 + 3(3) = 15 |

Now, filling out the table:

| Time in weeks | Dollars in the piggy bank | |---------------|----------------------------| | 0 | 6 | | 1 | 9 | | 2 | 12 | | 3 | 15 |

Next, we can represent this information in a graph and provide a corresponding equation, if you would like!
