is continuous on [0, 3] and differentiable on (0, 3), so the mean value theorem applies here. It says that there is some
in the open interval (0, 3) such that

We have

so

Step-by-step explanation:
the common increment is 20
Note: Steps of student are not given. So, the proper steps of the solution are provided below.
Given:
The inequality is

To find:
Where the student made any errors?
Solution:
We have,

On dividing both sides -5 change the sign of equality because -5 is a negative number.


Therefore, the solution of given inequality is
.
The answer would be 300 since the 3 is in the hundreds place.
