Your class grade consists of 40% homework, 25% quizzes and 35% final exam. suppose you have earned 95% in homework and 84% in quizzes entering the final exam. what percentage do you have to earn in the final in order to have an 87% overall percentage?

The earning would be approximately 79.29 % in the final exam

Step-by-step explanation:

Given,

In class grade the percentage of homework = 40 % = 0.40 ,

Percentage of quizzes =  25 % = 0.25,

Percentage of final exam = 35 %=0.35,

Also, there is an earning of 95% in homework and 84% in quizzes entering the final exam,

⇒ Earning in homework = 95 % of 0.40,

And, earning in quizzes = 84 % of 0.25

Let x be the percentage do you have to earn in the final in order to have an 87% overall percentage,

Hence, the earning would be approximately 79.29 % in the final exam in order to have an 87% overall percentage.
