This is the only question on my homework that I have no idea where to start. I'm probably making it harder than it really is. It states:
The scores of a student on the first seven of eight quizzes are: 62,68,50,58,58,54,70
A mean average of 54 on the eight quizzes is required to pass the course.
a.) What grade must she receive on the last quiz to pass the course?
b.) A quiz average of 61 is needed to get a B+ for this course. What grade must she receive on the last quiz to get a B+ for the course?
c.) Suppose the lowest quiz is dropped and the average is taken from the remaining seven quizzes. What grade must she receive on the last quiz to get a B+ for the course?
Any help is appreciated. Thank you!
