To determine the change in profit per product sold as the number of products sold increases from 400 to 500, we can look at the points given on the graph.
At 400 products sold, the profit per product is approximately 30 dollars. At 500 products sold, the profit per product is approximately 25 dollars.
Since the profit per product decreases from 30 to 25 dollars when moving from 400 to 500 products sold, the correct answer would be:
Enter 2 if the profit amount per product sold will decrease.
