Answer:
Graph D
Step-by-step explanation:
Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
Let, the Total students = x
It would be: x * 35% = 105
x * 0.35 = 105
x = 105 / 0.35
x = 300
Now, 20% would be: 300 * 0.20 = 60 students
In short, Your Answer would be Option B
