The horizontal axis shows days ranging from 0 to 28 in increments of 7. The vertical axis shows the cost in dollars ranging from 0 to 70 in increments of 7. Four data points are plotted on the graph at left parenthesis 0 comma 0 right parenthesis, left parenthesis 7 comma 21 right parenthesis, left parenthesis 14 comma 42 right parenthesis, and left parenthesis 21 comma 63 right parenthesis. A line connects all the data points. The second graph shows cost per day in dollars for option B. The horizontal axis shows days ranging from 0 to 20 in increments of 5. The vertical axis shows the cost in dollars ranging from 0 to 60 in increments of 20. Four data points are plotted on the graph at left parenthesis 0 comma 0 right parenthesis, left parenthesis 5 comma 20 right parenthesis, left parenthesis 10 comma 40 right parenthesis, and left parenthesis 15 comma 60 right parenthesis.

To determine which option is the better buy, we need to compare the cost per day for both options over the same number of days.

From the data points:

Option A costs:
- 7 days: $21
- 14 days: $42
- 21 days: $63
Option B costs:
- 5 days: $20
- 10 days: $40
- 15 days: $60

If we look at the cost per day for each option, we can see:

Option A:
- $21/7 days = $3 per day
- $42/14 days = $3 per day
- $63/21 days = $3 per day
Option B:
- $20/5 days = $4 per day
- $40/10 days = $4 per day
- $60/15 days = $4 per day

Based on the costs per day, Option A costs $3 per day, while Option B costs $4 per day. Therefore, Option A is the better buy.

So, the answer is 1 (Option A).
