This is the grading rationale for Mrs. Smith's French class: test: 45%, quizzes: 30%, homework: 25%. Joey has an 80% test average, 85% quiz average and 65% homework average. What is Joey's quarter grade

Respuesta :

Answer:

77.75%

Step-by-step explanation:

We just have to find the sums of the product of Joey's averages and their contribution to the total grade.

Test: 0.45 * 0.8 = 0.36 = 36%

Quizzes: 0.3 * 0.85 = 0.255 = 25.5%

Homework: 0.25 * 0.65 = 0.1625 = 16.25%

Total: 36% + 25.5% + 16.25% = 77.75%
