825
You just multiply 1000 × 0.825 = 825 students
We find the average by adding up all the students and dividing them by the number of classes she has. 19 + 13 + 19 + 9 + 14 + 15 is 89, and that divided by 6 is approximately 14.8, rounded to the nearest tenth.

"more" means added to, or addition. So 8 more than 'x' is:
x + 8
If you would like to solve (x^2 + 5x - 36) / (x + 9), you can do this using the following steps:
a = ?
(x + 9) * (x + a) = <span>(x^2 + 5x - 36)
x^2 + ax + 9x + 9a = x^2 + 5x - 36
ax + 9x = 5x
a + 9 = 5
a = 5 - 9
a = - 4
The correct result would be x - 4.
