Question

I really need help on this:

Answer 1

Explanation:

For (a), draw a horizontal line that crosses 1600 on the y-axis and the graph.

For (b), find the x coordinates of the point that makes the y coordinates 1600. So the coordinates would be (420,1600) which means that he needs to sell 420 boxes.

For (c), mark the spot between 360 and 480 and write 420 under it.
