To find the percent decrease, we need to find the difference between the regular price and the sale price. In this case, the regular price is $180 and the sale price is $680.40.
The difference between the regular price and the sale price is $680.40 - $180 = $<<680.4-180=500.4>>500.4.
To find the percent decrease, we need to divide the difference by the regular price and then multiply by 100.
So, the percent decrease is ($500.4/$180) * 100 = 277.33%.
Therefore, the percent decrease of the sale price from the regular price is 277.33%.
