Question

A buyer purchases 20 percent of the 12000 widgets in a warehouse's inventory. The next day, another

buyer purchases 10 percent of the remaining widgets. How many widgets are left in the warehouse?

Answer 1

20 percent of 12,000 is 2,400 so 12,000-2,400 = 9,600 and 10 percent of 9,600 is 960 so 9,600-960 = 8,640
