The document explains how to calculate a student's overall grade based on weighted averages from two 9-week grading periods and a final exam. It provides examples of calculating grades for two students, JB and KC, based on their scores for each grading period and exam. The weightings and scores are plugged into a formula to determine the overall grade. Step-by-step workings are shown to demonstrate how to set up and solve the formula. Additional practice problems are included for the reader to work through using the same process.

1. WEIGHTED AVERAGES How grades are calculated .. In college!!

6. Step 4 Put the values in the formula and solve: 1 st 9 weeks = .40 * .82 = 0.328 Now just add the results 2 nd 9 weeks = .40 * .75 = 0.30 Final = .20 * .80 = 0.16 0.328 + 0.30 + 0.16 = g 0.328 + 0.30 + 0.16 = .788 or 78.8% .788

11. Step 4 Put the values in the formula and solve: 1 st 9 weeks = .30 * .90 = 0.27 Now, just add the answers. 2 nd 9 weeks = .30 * .90 = 0.27 Final = .40 * .80 = 0.32 0.27 + 0.27 + 0.32 = g 0.27 + 0.27 + 0.32 = 0.86 0.86

12. Your turn… If TJ has a 80% average for the 1st 9 weeks and a 90% average for the 2nd 9 weeks, and 85% on the final exam. The grades are weighted as follows: each 9 weeks 30 % and the final exam 40%. What is her final grade?

13. Your turn… If Renetia has a 60% average for the 1st 9 weeks and a 90% average for the 2nd 9 weeks, and 85% on the final exam. The grades are weighted as follows: each 9 weeks 40 % and the final exam 20%. What is her final grade?

14. Your turn… If Devin has a 60% average for the 1st 9 weeks and a 90% average for the 2nd 9 weeks, and 85% on the final exam. The grades are weighted as follows: each 9 weeks 25 % and the final exam 50%. What is his final grade?
