Based on the following graph (which summarizes the demand, marginal revenue, and relevant costs for your product), determine your firms optimal price, output, and the resulting profits for each of the following scenarios:

"The horizontal axis labeled quantity ranges from 0 to 15 in increments of 1. The vertical axis labeled price ranges from 0 to 110 in increments of 10. A line labeled M R begins at the point (0, 100) goes down to the right and ends at the point (5, 0). A second line labeled D begins at the point (0, 100) goes down to the right and ends at the point (10, 0). A horizontal line labeled M C = A C passes through the point (0, 20) and intersects the line M R at (4, 20) and the line D at (8, 20)."
