Problem 44960. Rescale Scores

Each column (except last) of matrix X contains students' scores in a course assignment or a test. The last column has a weighted combination of scores across all the assignments and tests.
Replace the elements in the last column of this matrix with a GPA calculated based on the following scale:
Score GPA
91 - 100 3 - 4
81 - 90 2 - 3
71 - 80 1 - 2
61 - 70 0 - 1
Below 60 0
Assume that no student in this class has scored below 60. Also note that the mapping in the range [60, 100] is linear.
Example
Input:
100 90 95 95
70 50 60 60
80 70 90 80
Output:
100 90 95 3.5
70 50 60 0.0
80 70 90 2.0
