Answer 2

The percentage decrease of sale price from regular price is equal to 10%

Solution:

The regular sale price of the sofa, as mentioned in the question, is equal to $420.

The current sale price of the sofa is equal to $378

Thus, the difference in price is equal to:

Regular Price - Selling Price = 420 - 378 = 42

The percentage decrease of the sale price from regular price is equal to

`\text { percentage decrease }=\frac{\text { Difference in Price }}{\text { Regular Price }} * 100`

`(42)/(420) * 100=10`

Therefore, the percentage decrease of sale price i.e., $ 378 from regular price $ 420 is equal to 10%.
