## Reverse Percentages Formula

### Percentage Type Decrease

To calculate the percentage decrease, determine the percentage of the number that you want to decrease. Then subtract the decrease from the original number.
Example: A truck is reduced by 10% in price to \$ 40,000. What was the original price?
Step 1: The percentage of the original number is 100 - 10 = 90%
Step 2 Convert percent to a decimal: 90% = 90 ÷ 100 = 0.9
Step 3 Divide final number by decimal: 40,000 ÷ 0.9 = \$ 44,444

### Percentage Type Increase

To calculate the percentage increase, define the percentage of the number or price you want to increase, then add the result to the original price.
Example: Ramy invests money in cryptocurrency. Five years later, she sells them for \$7000 at a profit of 25% of their original value. How much did she spend on the cryptocurrency?
Step 1: The percentage of the original number is 100 + 25 = 125%
Step 2 Convert percent to a decimal: 125% = 125 ÷ 100 = 1.25
Step 3 Divide final number by decimal: 7000 ÷ 1.25 = 5600
