To find the percent decrease, we need to find the difference between the regular price and the sale price, then divide that by the regular price and multiply by 100%.
Regular price - Sale price = $810 - $680.40 = $129.6
Percent decrease = (difference / regular price) x 100% = ($129.6 / $810) x 100% = 0.16 x 100% = 16%
The percent decrease of the sale price from the regular price is 16%.
A sofa regularly sells for $810. The sale price is $680.40. Find the percent decrease of the sale price from the regular price
