Question

Ellen makes and sells bookmarks. She graphs the number of bookmarks sold compared to the total money earned. What is the rate of change for the function graphed to the left?

Answer 1

5/2 is the answer on edgeuity

Answer 2

The answer will be 5/2. You need to plot a graph in such a way that bookmark sold falls on the x-axis while money earned comes on the y-axis.

If you plot the values clearly then it will come out as, (4, 0), (8, 10), and (12, 20).

The terms will be able to give you the average cost.
