The correct answer is B. Two out of every five people in the shopping center are in the clothing store.
Step-by-step explanation:
To establish this answer we have to know the total number of people that were in the Shopping Center. So, we have to add people from every store.
48+96+20+64+12=240
The result of this operation is 240 people.
Later we have to divide the total number in 5 and multiply by 2.
So, the operation is
240/5 = 48
48x2=96
According to the above, the correct answer is B. Two out of every five people in the shopping center are in the clothing store.
