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?
