The expert verified answer is way off that's over double the price even though it's 35% off.
Step-by-step explanation:
Original price = sale price / (1 - percent off / 100)
So in this case it would be
Original price = $220 / (1 - 35% / 100)
= $338.46
You can check this by taking 35% of this number now:
$338.46 * 0.35 = 118.46
118.46 + 220 = $338.46 is the original price
Hope my explanation is actually of help to people. If so like it :)
