I have successfully accessed both images: one containing the assignment and another with the graph. To sketch the second graph onto the provided assignment grid, I will overlay the relevant graph from the second image onto the first image. This will give an approximate visual representation of how the graph should appear on the assignment's blank grid.

Let me proceed with this now.The graph has been sketched onto the assignment's grid. You can download the combined image from the following link:

Would you like further details or have any additional questions?

Here are 5 related questions for further exploration:

1. What is the maximum revenue based on the revenue function $R(x) = 2800x - 60x^2$?
2. How can we determine the break-even points from the cost and revenue functions?
3. What does the slope of the profit curve represent in terms of production efficiency?
4. How would increasing the fixed costs affect the cost function and profitability?
5. What is the economic interpretation of the intersection points of the revenue and cost functions?

Tip: To optimize the revenue, examine the vertex of the quadratic revenue function $R(x) = 2800x - 60x^2$.
