Final answer:
The student's overall grade is calculated using a weighted average, which results in a grade of 93, corresponding to answer option b) 92.
Step-by-step explanation:
The overall grade of the student can be calculated by taking weighted average of the formative and summative grades they have earned. As formative assignments make up 80% of the grade, and summative assignments account for 20%, the calculation would be as follows:
(Formative Grade × Formative Weight) + (Summative Grade × Summative Weight) = Overall Grade
(96 × 0.80) + (79 × 0.20) = 76.8 + 15.8 = 92.6
The student’s overall grade would be 92.6, which, when rounded to the nearest whole number, is 93. Therefore, the correct answer is b) 92.
