Question

Mr. See weights his grades. Tests are worth 60%, quizzes are worth 25% and homework is 15%. Joey's test average is an 82, his quiz average is a 77, and his homework average is a 98. What is Joey's current grade?

Answer 1

Joey's current grade based on the weighted averages of his tests, quizzes, and homework is 83.15%.

Step-by-step explanation:

To calculate Joey's current grade, we'll need to apply the weighted average formula based on the weightings given by Mr. See: tests are worth 60%, quizzes are worth 25%, and homework is 15%.

• First, multiply each average by its respective weight:
• Test average: 82 × 0.60 = 49.2
• Quiz average: 77 × 0.25 = 19.25
• Homework average: 98 × 0.15 = 14.7
• Next, add the results together to get Joey's weighted average:
• 49.2 + 19.25 + 14.7 = 83.15

Joey's current overall grade in the class is 83.15%.

Answer 2

83.15

Step-by-step explanation:

Joey's current grade can be determined by weighting his scores with the weights given and adding the results

Tests = 0.6 x 82 = 49.2

Quizzes = 0.25 x 77 = 19.25

homework = 0.15 x 98 = 14.7

49.2 + 19.25 + 14.7 = 83.15
