Answer :
There is a decrease of 20% from ÂŁ800 to ÂŁ640.
A change from 800 to 640 represents a negative change (decrease) of -20% Using the formula :
Percent change = [(800 - 640) / 800] x 100 = -20 % (decrease)
800 is the old value and 640 is the new value. In this case we have a negative change (decrease) of -20 percent because the new value is smaller than the old value.

Answer: Percentage change =20 % decrease
Step-by-step explanation:
Given original price =£800
New price= £640
Now change in price = £800 - £640
= £160
Since the new value is less than the old value so the percentage change will be negative i.e. decrease in percentage
Percentage change = (Change in Price/ Original Price)× 100
% change= (£160/£800)×100
=[tex]\frac{1}{5}\times 100[/tex]
=20 %
Hence percentage change in price = 20% decrease
