steposvetlana [31]

-10grade/week

Explanation:

Given parameters:

Initial grade = 95grade

Final grade = 65grade

Time = 3weeks

Unknown parameter:

Rate of change of grade = ?

Solution:

Rate is defined as the change of a quantity with time.

Rate of change of grade = $\frac{Final grade - Initial grade}{Time}$

Rate of change of grade = $\frac{65 - 95}{3}$ = $\frac{-30}{3}$

Rate of change of grade = -10grade/week

The rate of change of the student's grade is -10grade/week. It implies that the grade of the student reduces by 10unit per week.
