+1904 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?
