Question 897998: A student receives marking period grades of 52, 64, 70, and 53. Each marking period grade is worth 20 percent of the final average. The student receives a 72 on the midterm exam, which is worth 10 percent of the final average. What is the minimum numerical grade (must be a whole number) that the student needs on the final exam to pass the course if the final exam is also worth 10 percent of the final average? Use the fact that 64.5 is a passing score.

(52+64+70+ 53)*.20=47.8
72*.10=7.2
47.8+7.2=55
64.5-55=9.5
.10*95=9.5
He needs 95 get 64.5
Not too surprising!
He failed three out of 4 marking periods.
His highest grade has been 72.
There is basically no chance that he will pass.
