Answer:
The unit cost per rubber tile is $6.
Explanation:
The unit cost per rubber tile is equal to the slope of the line in the graph.
So, the slope can be calculated using 2 points of the line as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x1, y1) and (x2, y2) are the coordinates of the points in the line. Then, we can replace (x1, y1) by (2, 12) and (x2, y2) by (4, 24) to get:
[tex]m=\frac{24-12}{4-2}=\frac{12}{2}=6[/tex]
So, the unit cost per rubber tile is $6.
