Step-by-step explanation:

First: work out the difference (decrease) between the two numbers you are comparing. Then: divide the decrease by the original number and multiply the answer by 100. If your answer is a negative number then this is a percentage increase.

Given:

A shop had 3200 customers last month and 3088 customers this month.

To Find:

Percentage decrease in the number of customers.

Solution:

Number of customers last month = 3200

Number of customers this month = 3088

Decrease in the number of customers = 3200 - 3088

                                                                = 112

Percentage decrease = [tex]\frac{\text{Decrease in the number of customers}}{\text{Number of customers last month}}\times 100[/tex]

                                    = [tex]\frac{112}{3200}\times 100[/tex]

                                    = 3.5%

Therefore, percentage decrease in the number of customers will be 3.5%.
