Question

On a graph y total cost
X number of markers
A is 3,6
B is 6,3
Predict what the total cist would be for buying 10 of the type A markers
A. 20.00
B. 0.50
C. 2.00
D. 5.00

Answer 1

To predict the total cost for buying 10 of the type A markers, we need to understand the coordinates of points A and B on the graph. The point A (3,6) suggests that when 3 markers (x-axis value) are purchased, the total cost is 6 (y-axis value).

From point A, we can determine the cost per marker for type A:

- Cost for 3 markers = 6
- Cost per marker = Total cost / Number of markers = 6 / 3 = 2.

Now, to find the total cost for 10 markers of type A:

- Total cost = Cost per marker * Number of markers = 2 * 10 = 20.

So, the predicted total cost for buying 10 of the type A markers is **A. 20.00**.
