Research indicates that the leading brand of laundry detergent accounted 35% of 400,000 total sales in the marketplace. How many sales were made by all the other brands combined? SHOW WORK

400,000 x 0.35 = 140,000

400,000 - 140,000 = 260,000

The other brands combined made 260,000 sales.

To find out how many sales were made by all the other brands combined, we first need to determine the sales made by the leading brand of laundry detergent. We can calculate this by multiplying the total sales by the percentage accounted for by the leading brand.

Total sales by the leading brand = 400,000 sales * 35% = 140,000 sales

Now, to find the sales made by all the other brands combined, we subtract the sales of the leading brand from the total sales.

Sales made by all other brands combined = Total sales - Sales made by the leading brand
Sales made by all other brands combined = 400,000 sales - 140,000 sales
Sales made by all other brands combined = 260,000 sales

Therefore, all the other brands combined made 260,000 sales.
