Question

Andrew took a survey of his friends to find out their favorite type of music. Of the 34 friends surveyed, 22 said they liked rock music the best. What percent like rock music the best?

Step-by-Step Solution

Answer

About 64.7% like rock music the best.

Step 1. Given information.

Andrew took a survey of his friends to find out their favorite type of music.

The part is 22 and the base is 34.

Step 2. Consider the variable.

Consider p be the percent.

Use the formula such that,

$\frac{a}{b}=\frac{p}{100}$

Step 3. Determine the percent.

Substitute $a=22,b=34$ in $\frac{a}{b}=\frac{p}{100}$.

$$\begin{gathered} \frac{22}{34}=\frac{p}{100} \\ 34p=2200 \\ p=\frac{2200}{34} \end{gathered}$$

So, $p=64.7$.
