To determine the number of products a business needs to sell to achieve maximum profit per product, you would typically look for the peak point (maximum) on the graph that plots profit per product against the total number of products sold.
In mathematical terms, if the profit per product is represented as a function \( P(x) \), where \( x \) is the number of products sold, you would find the maximum value of \( P(x) \) within the range of the graph.
If you have the graph or data points, you could either:
- Identify the maximum point visually on the graph.
- If a mathematical equation relates profit per product to the number of units sold, you could use calculus techniques to take the derivative and set it to zero to find critical points, then use the second derivative test to confirm whether it’s a maximum.
If you need a specific numerical answer, please provide the graph or relevant data.
