What is the discount on a vest that normally sells for 21$ but is now 25% off show work on how you got your answer

The vest will now cost $15.75. To find the amount that will be discounted you will multiply 21 by .25 (25% in decimal form) to get 5.25. That is the amount of money that will be discounted from the vest. So subtract 5.25 from 21, and you get 15.75, which is how much the vest costs after discount. Hope this helps!
