To determine which option is the better buy, we need to consider the cost per day for each option.
Looking at the graphs, for Option A, the cost per day starts at $0 and increases by $21 for every 7 days. Thus, the cost per day for Option A is $21/7 = $3.
For Option B, the cost per day starts at $0 and increases by $20 for every 5 days. Thus, the cost per day for Option B is $20/5 = $4.
Comparing the cost per day, we can see that Option A has a lower cost per day ($3) compared to Option B ($4). Therefore, Option A is the better buy.
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.
