To find the profit when the selling price is $10 based on the graph of the function \( P(s) \), you would typically look for the point on the graph where the selling price \( s \) is equal to 10 and then read the corresponding profit value \( P(s) \).
Since I cannot see the graph, I am unable to provide a specific profit value. However, you can determine the profit by locating the point where the selling price is $10 on the x-axis of the graph and reading the value of \( P(s) \) on the y-axis directly above.
Please check the graph for the value of profit at \( s = 10 \), and it should match one of the given response options.
