Question

In a recent survey of college-educated adults, 210 indicated that they regularly work more than 50 hrs a week. If this represents 35% of those surveyed, how many people were in the survey?

Answer 1

We are given that there are 210 people representing 35% of a survey. To determine the total number of people "x" we will use the following relationship:

`x*(35)/(100)=210`

Now we solve for "x" first by multiplying both sides by 100:

`\begin{gathered} x*35=210*100 \\ x*35=21000 \end{gathered}`

Now we divide both sides by 35:

`\begin{gathered} (x*35)/(35)=(21000)/(35) \\ x=600 \end{gathered}`

Therefore, there were 600 people in the survey.
