To determine which graph accurately represents Jane's savings over time, we need to analyze her savings account activity:
- Initial Deposit: Jane starts with $200.
- Monthly Deposit: She deposits an additional $100 every month.
We can calculate her total savings at the end of each month:
- Month 0: \( 200 + 0 \times 100 = 200 \)
- Month 1: \( 200 + 1 \times 100 = 300 \)
- Month 2: \( 200 + 2 \times 100 = 400 \)
- Month 3: \( 200 + 3 \times 100 = 500 \)
- Month 4: \( 200 + 4 \times 100 = 600 \)
- Month 5: \( 200 + 5 \times 100 = 700 \)
- Month 6: \( 200 + 6 \times 100 = 800 \)
Now let's compare the graphs based on the calculated points:
- (0, 200)
- (1, 300)
- (2, 400)
- (3, 500)
- (4, 600)
- (5, 700)
- (6, 800)
From the descriptions of the provided graphs, the correct graph should show the points calculated above:
- The second graph shows:
- \( (0, 200) \)
- \( (1, 300) \)
- \( (2, 400) \)
- \( (3, 500) \)
This graph shows the correct increases each month, indicating that Jane adds $100 monthly in addition to her initial deposit.
Therefore, the second graph correctly illustrates how much money will be in her savings account over time.
