Actually Welcome to the Concept of the Functions.
so after plotting the graphs, we get as,
==> m = 2.5
==> b = 0
==> y = mx+c
a straight line
If 3/7 are boys, then 4/7 have to be girls.
2282 / 7 = 326
326 x 4 = 1304
There are 1304 girls.
1) 12
2) 2y
3) 12+2y
4) 12+2y
3/12
5/12
9/24 or aka 3/8
7/24
13/36
11/36
