You work at an appliance store that offers an extended warmanty on each product sold. The store sold 12,930 appliances and two-fifths of the customers purchased the extended warranty. How many extended warrantles were purchased?

5,172

Step-by-step explanation:

When figuring out a fraction of a number (especially of total things sold to find out the number of a certain thing purchased), remember that you are multiplying. So when finding 2/5 of 12,930, just multiply 12,930 by 2/5 (or, in decimal form, .4) and that will give you 5,172. Hope this helps!
