Answer: 10
Step-by-step explanation:
To find the average selling price per unit for the product, you can divide the total sales by the number of units sold. In this case, with 9 times 10 dollars in sales, if we assume that each "time" represents a unit sold, then the total sales would be 9 * 10 = 90 dollars. If we also assume that 9 units were sold, then the average selling price per unit would be 90 / 9 = 10 dollars.
