Answer: 400 Shoppers
Step-by-step explanation:
Given
156 people spent the night in Wal-mart
These 156 people represent 39% of total shoppers at Wal-mart
Suppose x is the total no of shoppers at Wal-mart
So, we can write
[tex]\Rightarrow 39\%\ \text{of}\ x=156\\\Rightarrow 0.39\times x=156\\\\\Rightarrow x=\dfrac{156}{0.39}=400\ \text{People}[/tex]
