Use the image to answer the question.

An illustration shows two graphs depicting cost per day in dollars for options A and B. The first graph shows cost per day in dollars for option A. 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. A line connects all the data points.

Two options for passes to ride public transportation are displayed in the graphs. Is Option A or Option B the better buy? Choose 1 for Option A and 2 for Option B.

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

From the first graph, we can see that Option A has a cost of $21 per day after 7 days, $42 per day after 14 days, and $63 per day after 21 days.

From the second graph, we can see that Option B has a cost of $20 per day after 5 days, $40 per day after 10 days, and $60 per day after 15 days.

Comparing the costs, we can see that Option B has a lower cost per day for all given durations. Therefore, Option B is the better buy.

So, the answer is 2 for Option B.

To determine which option is the better buy, we need to compare the cost per day for both Option A and Option B.

Option A:
- The graph shows the cost per day in dollars for Option A.
- The data points and the line connecting them represent the cost per day for Option A.
- The cost ranges from $0 to $70 per day, with increments of $7.
- The data points are: (0,0), (7,21), (14,42), and (21,63).

Option B:
- The graph shows the cost per day in dollars for Option B.
- The data points and the line connecting them represent the cost per day for Option B.
- The cost ranges from $0 to $60 per day, with increments of $20.
- The data points are: (0,0), (5,20), (10,40), and (15,60).

To compare the two options, we need to consider the cost per day. Looking at Option A, the cost increases by $21 every 7 days. In comparison, Option B has a higher increase of $20 every 5 days.

By analyzing the data, we can conclude that Option B offers a better buy. Therefore, the answer is 2 for Option B.
