To predict the total cost for buying 10 of type A markers based on the graph you described, we need to analyze the given information about lines A and B.
-
Line A: Looks like it indicates a cost for markers up to 6. Given that it starts at 0 and angles up, we can infer that it represents a certain cost per marker.
-
Line B: This line seems to represent a different cost for markers, starting at a higher cost than Line A.
Since the question asks for the total cost of buying 10 markers, we need to assume that the cost per marker from the graph continues in a linear fashion beyond what is presented on the chart up to 6 markers — or we need to refer to the costs given in the options.
Let's consider the options provided:
- $2.00
- $5.00
- $20.00
- $0.50
If we assume that these costs represent the unit cost of markers:
- At $0.50 per marker, 10 markers would cost 10 * $0.50 = $5.00.
- At $2.00 per marker, 10 markers would cost 10 * $2.00 = $20.00.
- At $5.00 per marker, 10 markers would cost 10 * $5.00 = $50.00.
- At $20.00 per marker, 10 markers would cost 10 * $20.00 = $200.00.
Since all costs besides $0.50 and $2.00 lead to unrealistic prices for 10 markers considering the context of the options and the graph's settings, it is reasonable to suggest that the line slopes indicate a cost of either $0.50 or $2.00.
Without more specific data from the graph's lines for the costs, we can conclude that:
- $0.50 seems unlikely since it suggests a very low cost.
- $2.00 can be a reasonable prediction based on common market prices.
Thus, the best prediction from the choices provided for the cost of 10 markers is:
$20.00 (assuming a cost of $2.00 per marker).
