Percentages
We are given the final price of a sofa after a discount of 62% was applied.
Assume the original (regular) price of the sofa was 100%.
If it was discounted 62%, then its new price is 100% - 62% = 38%
The discounted price is $144.40. To find the original price, we just divide:
$144.40 / 0.38
Recall that a percent number is expressed in decimal by dividing it by 100, that is why I got 38 / 100 = 0.38
Calculating the division:
$144.40 / 0.38 = $380
The regular price was $380
