If there are 420 students surveyed, which equation can be used to find the number of students s who prefer rap? Pop: 5/8 Jazz: 1
Aleksandr [31]

Answer:

B. s=\dfrac{1}{4}\times420

Step-by-step explanation:

Total number of students surveyed = 420

Of which only \dfrac{1}{4} prefer rap.

So, the number of people who like rap is the product of the fraction of people who prefer rap and the total number of students.

\text{Number of students who prefer rap}=s=\dfrac{1}{4}\times420\\\Rightarrow s=105

The number of students that prefer rap is 105

So the equation is s=\dfrac{1}{4}\times420.
