To determine the profit when the selling price is $10 based on the graph, you would need to locate the point on the graph where the selling price \( s \) is equal to $10 and then find the corresponding value of the profit \( P(s) \) on the vertical axis.
Since I don't have access to the graph itself, I cannot see the specific values to determine the profit at that price. However, you can obtain this information by identifying the point on the graph at \( s = 10 \) and reading off the value of \( P(s) \).
Please check the graph at \( s = 10 \) to find the correct profit value among the options provided.
