How To Calculate An Original Amount Using Reverse Percentages

How To Calculate An Original Amount Using Reverse Percentages To calculate a reverse percentage using algebra: write the original amount required as ‘𝑥’. write the percentage multiplier multiplied by ‘𝑥’ equal to the new amount. divide both sides by the percentage multiplier to calculate the original amount ‘𝑥’. for example: a car is sold at a 15% discount for $6800. Finding the reverse percentage of a number in 3 easy steps. step 1) get the percentage of the original number. if the percentage is an increase then add it to 100, if it is a decrease then subtract it from 100. example: if the percentage is an 18% increase, then the percentage is 100 18 = 118%. example: if the percentage is a 37% decrease.
