Camille receives a piggy bank containing 4 dollars for her birthday. Every week, Camille adds 8 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.

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.
