So 2/3 of her students do NOT walk to school
of those (4/5) take the bus
so (4/5)(2/3) or 8/15 take the bus
The number of students must be a multiple of 15
In an enlightened board of education she would have 15 students,
in reality she probably has 30 students,
and , in some backwards regions, she could have 45 students.
