Last year, a quarter of the students in your class played a ninstrument. This year,
6
students
joined
the
to classify.
Four
of the
New
students
to play
a
instrument.
Now,
a
third
of
the
students
to play
a
instrument.
How
many
students
are in
your
to classify
now
18, 24, 30 or 48? Initial number of students = x
original number playing = x/4
This year:
number of students = x+6
playing number = x/4 + 4
x/4 + 4 = (1/3)(x+6)
times 12
3x + 48 = 4x + 24
-x = -24
x = 24
So now there are x+6 or 30 students in the class Thank you very much! KOWALSKI, ANALASIYSSFJSIOJF.
