There was an increase of 33.33% in Miss Williamson‘s homeroom

Step-by-step explanation:

Percentage increase in the number of students=((Final number-Initial number)/Initial Number)×100

where;

Initial number of students=18 students

Final number of students=24 students

Replacing;

((24-18)/18)×100=(6/18)×100=33.33% increase

There was an increase of 33.33% in Miss Williamson‘s homeroom

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
