Question

Use the image to answer the question.

An illustration shows quadrant one of a coordinate plane where the x-axis and y-axis range from 0 to 6 in increments of 1. The y-axis is titled total cost in dollars and the x-axis is titled number of markers. A solid line, labeled A, is marked on the graph and passes through coordinates left parenthesis 0 comma 0 right parenthesis and left parenthesis 3 comma 6 right parenthesis. A dotted line, labeled B, passes through coordinates left parenthesis 0 comma 0 right parenthesis and left parenthesis 6 comma 3 right parenthesis.

Predict what the total cost would be for buying 10 of the type A markers.

Answer 1

From the description of the graph, we have the following information regarding line A, which represents the cost of markers:

- The line A passes through the points \( (0, 0) \) and \( (3, 6) \). This indicates that 3 markers cost $6.

To find the cost per marker, we can calculate it as follows:

\[
\text{Cost per marker} = \frac{\text{Total cost}}{\text{Number of markers}} = \frac{6}{3} = 2 \text{ dollars per marker}
\]

Now, to find the total cost for buying 10 markers, we multiply the cost per marker by the number of markers:

\[
\text{Total cost for 10 markers} = 10 \times 2 = 20 \text{ dollars}
\]

Based on this calculation, the total cost for buying 10 of the type A markers would be:

**$20.00**
