Final score of N is 81.8
Final score of J is 94.5
Explanation of Solution
Given information:
Student | Homework Grade (%) | Test Grade (%) | Quiz Grade(%) | Final grade |
B | 94 | 88 | 100 | |
N | 82 | 78 | 91 | |
J | 90 | 97 | 95 |
Homework is 30%, test is 50% and quiz is 20%
Calculation:
For B,
Final grade is 30% of 94+ 50% of 88 + 20% of 100
So,
=
And,
=
Hence, final score of B is 92.2
For N,
Final grade is 30% of 82+ 50% of 78 + 20% of 91
So,
=
And,
=
Hence, final score of N is 81.8
For J,
Final grade is 30% of 90+ 50% of 97 + 20% of 95
So,
=
And,
= 27+ 48.5+19
Hence, final score of J is 94.5
