use your formula and find the amount carly has saved after 1 year (hint 52 weeks in a year..)
after 52 weeks carly has saved ___

Answer 1

Carly's savings over time is indeed an example of linear change because she consistently adds the same amount of money ($50) to her savings every week. This means her savings grow at a constant rate, which is the hallmark of a linear relationship.

### Sequence of Carly’s Savings Over 8 Weeks:

1. **Week 1:** $50
2. **Week 2:** $100
3. **Week 3:** $150
4. **Week 4:** $200
5. **Week 5:** $250
6. **Week 6:** $300
7. **Week 7:** $350
8. **Week 8:** $400

So the sequence is: $50, $100, $150, $200, $250, $300, $350, $400

### Formula for Carly's Savings Over Time:

Let \( y \) represent the total savings and \( x \) represent the number of weeks. Since Carly adds $50 each week, the formula will be:
\[ y = 50x \]

### Amount Saved After One Year (52 Weeks):

Using the formula:
\[ y = 50x \]

Substituting \( x = 52 \):
\[ y = 50 \times 52 \]
\[ y = 2600 \]

So, after 52 weeks, Carly has saved **$2,600**.
