1/4 of the total girls = 16
1/4x = 16
x = 16 * 4
x = 64 girls 

1/8 of the total boys = 7
1/8x = 7
x = 7 * 8
x = 56 boys

for a total of (64 + 56) = 120 students <===

Answer:

The correct option is 3.

Step-by-step explanation:

From the given graph it is noticed that the related line passing through the point (-3,1) and (0,3).

If a line passing through two points, then the equation of line is

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

The equation of related line is

y-1=\frac{3-1}{0-(-3)}(x-(-3))

y-1=\frac{2}{3}(x+3)

y-1=\frac{2}{3}(x)+2

Add 1 on both the sides.

y=\frac{2}{3}(x)+2+1

y=\frac{2}{3}(x)+3

The equation of related line is y=\frac{2}{3}(x)+3.

The related line is a dotted line, it means the point on the line does not included in the solution set.

The shaded region is above the line so the sign of inequity is >.

The required inequality is

y>\frac{2}{3}(x)+3

Therefore option 3 is correct.
