Final answer:
Using the provided contribution margin of $100,000, which is 40% of store J's sales, it is calculated that store J's total sales were $250,000.
Step-by-step explanation:
To determine the total sales in store J for the Leso company, we need to use the information provided about the contribution margin. The contribution margin for store J is stated to be $100,000, which is 40% of store J's sales. This means that to find store J's sales, we can set up a proportion where 40% of sales equals the $100,000 contribution margin:
0.40 (Sales) = $100,000
To find the sales figure, we simply divide the contribution margin by the percentage (expressed as a decimal):
Sales = $100,000 / 0.40
Sales = $250,000
Therefore, the total sales in store J were $250,000.
