The answer is 16.67%
Step-by-step explanation:
Number of customers who visited in the first week = 360
Number of customers who visited in the second week = 300
Number of customers decreased in the second week =
![360-300=60](https://img.qammunity.org/2019/formulas/mathematics/middle-school/b72e1y65yoq0jdx3vyrqyja1sen4f8uqhn.png)
So, the percentage change of the number of customers that visited the store in the first week to the number of customers that visited the store in the second week will be =
![(60)/(360)*100 =16.67](https://img.qammunity.org/2019/formulas/mathematics/middle-school/uzs17t5eavpdrtw7fdgc9mapsbabee18bt.png)
