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 line is marked on the graph, passing through coordinates left parenthesis 0 comma 0 right parenthesis and left parenthesis 4 comma 3 right parenthesis.

Question

What is the unit cost from the graph?(1 point)

Answer 1

To find the unit cost from the graph, we can look at the coordinates through which the line passes, specifically the points (0, 0) and (4, 3).

The coordinates represent:

• (0, 0): This indicates that when 0 markers are purchased, the total cost is $0.
• (4, 3): This indicates that when 4 markers are purchased, the total cost is $3.

To determine the unit cost (cost per marker), we can calculate it using the total cost and the number of markers:

1. Total cost for 4 markers = $3
2. Number of markers = 4

Unit cost = Total cost / Number of markers = $3 / 4 = $0.75 per marker.

Thus, the unit cost from the graph is $0.75.
