The value of sales at a shop decreases from £145000 a year to £129000. Find the percentage decrease in the values of sales.

Percentage of decrease in Sales = 11.04% or 11 %

Step-by-step explanation:

Decrease Percentage = [ (Original Value - New Value) : Original Value] * 100

Percentage = [ (145,000 - 129,000) : 145,000] * 100

Percentage = [ (16,000) : 145,000] * 100

Percentage = (0.1104) * 100

Percentage of decrease in Sales = 11.04% or 11 %
