Answer 1

Let's create a table to represent the amount of money in Camille's piggy bank over time.

Camille starts with 4 dollars, and every week she adds 8 dollars. Thus, we can calculate the total amount in the piggy bank after 0, 1, 2, and 3 weeks:

**Time in weeks | Dollars in the piggy bank**
1. **0 weeks:**
- Starting amount: 4 dollars
2. **1 week:**
- Total = 4 + 8 * 1 = 4 + 8 = 12 dollars
3. **2 weeks:**
- Total = 4 + 8 * 2 = 4 + 16 = 20 dollars
4. **3 weeks:**
- Total = 4 + 8 * 3 = 4 + 24 = 28 dollars

Now filling in the table:

| Time in weeks | Dollars in the piggy bank |
|---------------|---------------------------|
| 0 | 4 |
| 1 | 12 |
| 2 | 20 |
| 3 | 28 |

This table shows the progression of the total amount of money in Camille's piggy bank over the first three weeks.
