Question

annette is surveying people in the city about their interest in a new shopping mall. she found that 180 people, or 37.5% of those surveyed, do not want a new mall. how many people did annette survey?

Explanation:

Step1: Set up the proportion

Let the total number of people surveyed be $x$. We know that 37.5% (or 0.375 in decimal form) of $x$ is 180. So the equation is $0.375x = 180$.

Step2: Solve for $x$

Divide both sides of the equation by 0.375: $x=\frac{180}{0.375}$.
$x = 480$.

Answer:

480
