there arre 221 students on a fiel trip five students ride in a van the rest of the students fill the 6 buses enter an equation t

iren2701 [21]

According to the question statement, the total sum of students is 221, which includes the students that ride on bus and the students that ride in a van.

The students that ride in a van are five, the students that ride on bus are 6 times s which is the product of the number of buses and the number of students that are on each bus.

Write all this information into an equation, this way:

$6s+5=221$

Now, solve the equation for s to find the number of students that are on each bus.

$\begin{gathered} 6s+5=221 \\ 6s=216 \\ s=\frac{216}{6} \\ s=36 \end{gathered}$

There are 36 students on each bus.
