<span>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.</span>
