Replacing the given values in formula (a) we have:
Amount Saved = Original Price x Discount in Percent / 100. So,
Amount Saved = 20 x 30 / 100
Amount Saved = 600 / 100
Amount Saved = $6 (answer).
In other words, a 30% discount for a item with original price of $20 is equal to $6 (Amount Saved).
Note that to find the amount saved, just multiply it by the percentage and divide by 100.
