A sofa regularly sells for $510. The sale price is $423.30. Find the percent decrease of the sale price from the regular price.
(510-423.30)/510 = 17%
To find the percent decrease of the sale price from the regular price, you can use the formula:
Percent decrease = ((Regular price - Sale price) / Regular price) * 100
Let's substitute the given values into the formula:
Regular price = $510
Sale price = $423.30
Percent decrease = ((510 - 423.30) / 510) * 100
Now, let's calculate the percentage decrease:
Percent decrease = (86.70 / 510) * 100
Percent decrease ≈ 17.00%
Therefore, the percent decrease of the sale price from the regular price is approximately 17.00%.
