percentage decrease
This means making something smaller by a certain percentage.
First, we calculate the decrease. Then, we subtract that decrease from the original sum.
For example, an insurance company is offering a decrease of 20% if a policy is arranged online.
Akeem needs to arrange a policy for his car.
The insurance company has offered him a policy for £300, and if he arranges it online he will receive a decrease of 20%.
Therefore, 20% of £300 = £60.
The price of Akeem’s policy, having arranged it online, is £300 – £60 = £240.
The opposite of ‘percentage decrease’ is ‘percentage increase‘.
We sometimes refer to ‘percentage decrease’ as ‘percentage reduction’.
