In 7th grade:
red-hair students =58
another color hair students =609
In 8th grade:
red-hair students =60
Let's assume
another color hair students =x
now, we are given
The numbers of red-haired students in 8th grade are proportional to the numbers in 7th
so,
[tex]\frac{60}{58} =\frac{x}{609}[/tex]
now, we can solve for x
we get
[tex]x=609*\frac{60}{58} [/tex]
we get
[tex]x=630 [/tex]
so, students have another color hair in 8th grade is 630.........Answer
