Question

Leah receives a piggy bank containing 20 dollars for her birthday. Every week, Leah adds 10 dollars to the piggy bank. Represent this situation with a table, a graph, and an equation.
Let’s start by representing this situation with a table. Start by finding the amount in the piggy bank after 0, 1, 2, and 3 weeks.

Answer 1

To create a table representing Leah's piggy bank situation, we begin with an initial amount of $20 and then add $10 for each subsequent week.

Let's calculate the amount in the piggy bank for 0, 1, 2, and 3 weeks:

- **Week 0**: Starting amount = 20 dollars
- **Week 1**: 20 + 10 = 30 dollars
- **Week 2**: 30 + 10 = 40 dollars
- **Week 3**: 40 + 10 = 50 dollars

Now we can fill in the table:

| Time in weeks | Dollars in the piggy bank |
|---------------|---------------------------|
| 0 | 20 |
| 1 | 30 |
| 2 | 40 |
| 3 | 50 |

### Summary of the table:
- After 0 weeks: $20
- After 1 week: $30
- After 2 weeks: $40
- After 3 weeks: $50

Next, we can create a graph and write the equation if you'd like! Would you like me to proceed with those?
