Answer 1

Step 1

Given; A college seminar has 64 registered participants. If only 44.4% show up for the lecture, how many total people were in attendance?

Step 2

We calculate thus;

`\frac{percentage\text{ that showed up}}{100}=\frac{People\text{ in attendance\lparen x\rparen}}{Total\text{ registered participants}}`
`\begin{gathered} (44.4)/(100)=(x)/(64) \\ 2841.6=100x \end{gathered}`
`\begin{gathered} x=(2841.6)/(100) \\ x=28.416 \\ x\approx28\text{ registered participants showed up} \end{gathered}`

Answer;

`About\text{ }28\text{ registered participants were in attendance}`
