Count the reduction of price
reduction = 20,000 - 17,250
reduction = 2,750
After find the amount of reduction, we count the precentage by this formula
percentage = reduction/old price × 100%
Now input the number to the formula
percentage = 2,750/20,000 × 100%
percentage = 11/80 × 100 %
percentage = (1,100/80) %
percentage = 13.75%
The decrease in the price is 13.75% from the regular price
