If I am a teacher and I am giving out four quizzes to my students, three of which are worth 60% of the overall grade and one worth 40% of the overall grade, and I get a 70%, an 80%, and a 60% on the quizzes worth 60% of the overall grade and I got a 90% on the quiz that is worth 40% of the overall grade, what grade did my student get?

The first 3 quizzes average =[60% + 70% + 80%] / 3 =70%

This 70% is worth 60% of the grade =.70 x . 60 =42% of the grade

The last 90% is worth 40% of the grade =0.9 x 0.4 =36% of the grade

42% + 36% =78% the overall grade of the students.
