To determine which scenario best describes the graph with a y-intercept of $30, we need to analyze the different scenarios provided based on the initial amount of savings and how much the savings increase each week.

1. **Juan starts with $30 in savings and increases his savings amount by $5 each week.**
- Initial savings: $30
- Weekly increase: $5
- Equation: \( y = 30 + 5x \)

2. **Juan starts with $30 in savings and increases his savings amount by $1 each week.**
- Initial savings: $30
- Weekly increase: $1
- Equation: \( y = 30 + 1x \)

3. **Juan starts with $5 in savings and increases his savings amount by $30 each week.**
- Initial savings: $5
- Weekly increase: $30
- Equation: \( y = 5 + 30x \)

4. **Juan starts with $5 in savings and increases his savings amount by $30 each week.**
- Initial savings: $5
- Weekly increase: $30
- Equation: \( y = 5 + 30x \)

5. **Juan saves $30 per week.**
- Assuming he starts with $0, the equation would be \( y = 30x \).

From the scenarios, the first two have a y-intercept of $30, meaning both begin from $30 in savings. The crucial difference is their week-to-week increase, which affects the slope of the line in the graph.

However, since the question states that the y-intercept is $30 and doesn't specify the weekly increase as a factor in determining the correct graph, either of the first two scenarios can accurately represent the graph with a $30 starting amount.

***In conclusion, either of the first two scenarios is correct regarding the y-intercept of $30:***

- Juan starts with $30 in savings and increases his savings amount by $5 each week.
- Juan starts with $30 in savings and increases his savings amount by $1 each week.

If you need to choose just one scenario with a stronger emphasis on savings being incremented regularly, the first option might be the most intuitive as it suggests a higher increase over time.

Given the information you've provided:

- The y-axis represents the savings amount, increasing in multiples of 10 up to 90.
- The x-axis represents time in weeks.
- After 4 weeks, Juan has $50 in savings.

From this, we can calculate the weekly savings increase.

1. **Starting Amount**: We still have the understanding that Juan starts with $30, as determined before.
2. **Amount After 4 Weeks**: Juan has $50.
3. **Calculate Total Increase in 4 Weeks**:
- Total amount gained in 4 weeks = $50 - $30 (initial savings) = $20.
4. **Weekly Savings Increase**:
- Weekly increase = Total increase / Number of weeks = $20 / 4 weeks = $5 per week.

Now we can set up the linear equation representing Juan's savings:

- Starting amount (y-intercept) = $30
- Increase per week (slope) = $5

So the equation for Juan's savings is:

\[ y = 30 + 5x \]

Where:
- \( y \) is the total savings after \( x \) weeks.

### Confirming the Scenario:
Using the equation, we can check the savings at various points:

- **At Week 0 (Start)**:
- \( y = 30 + 5(0) = 30 \)

- **At Week 1**:
- \( y = 30 + 5(1) = 35 \)

- **At Week 2**:
- \( y = 30 + 5(2) = 40 \)

- **At Week 3**:
- \( y = 30 + 5(3) = 45 \)

- **At Week 4**:
- \( y = 30 + 5(4) = 50 \)

This confirms that after 4 weeks, Juan indeed has $50 in savings based on the equation derived from the information provided.

### Conclusion:
The best scenario that describes the graph based on your inputs is:
- Juan starts with $30 in savings and increases his savings amount by $5 each week.

The graph would show a straight line starting at $30 and increasing by $5 for each subsequent week, consistent with the data provided.
