We have the following:
In this case, the first thing is to divide all the students into 4 groups, just like this
[tex]\frac{184}{4}=46[/tex]Then, since 8 students left in cars, now we must take the equal amount from each group, therefore
[tex]\frac{8}{4}=2[/tex]From each group we took 2 people, which means that 44 students would then leave each bus (46-2)
