Question

The grades in a university are calculated as follows: 30% from class assignments, 35% from the final exam, and 35% from the field project. If Jay scores 75 out of 100 in class assignments, 65 out of 100 in the final exam, and 72 out of 100 in the field project, what is his average score?

Answer 1

To calculate Jay's average score, multiply each score by its corresponding weight and add them together: 75 * 0.30 for class assignments, 65 * 0.35 for the final exam, 72 * 0.35 for the field project, resulting in an average score of 70.45.

Step-by-step explanation:

To calculate Jay's average score in the university, we will weigh his scores by the percentage that each component contributes to the final grade.

Jay scored 75 out of 100 in class assignments, which counts for 30% of the total grade, 65 out of 100 in the final exam, which represents 35% of the grade, and 72 out of 100 in the field project, which also represents 35% of the grade. Below is a step-by-step calculation:

1. Multiply his score in class assignments by 0.30 (the weight of the class assignments): 75 * 0.30 = 22.5
2. Multiply his score in the final exam by 0.35 (the weight of the final exam): 65 * 0.35 = 22.75
3. Multiply his score in the field project by 0.35 (the weight of the field project): 72 * 0.35 = 25.2
4. Add the weighted scores together to find Jay's average score: 22.5 + 22.75 + 25.2 = 70.45

Jay's average score is 70.45.
