Lets say i have a 90 percent in my class.

all of this 90 percent is coming from homework.

homework is worth 72 percent and The other 28 percent of your grade is the final exam.

the final exam is composed of 50 questions.

how many can i miss and still keep my A?

formula?

If A=90%...

You can miss 5 questions on the final exam

90% X 72 = 64.8

64.8 + x =90

x=25.2

25.2/28=90%

90% x 50 = 45

50-45 = 5 questions

HW + final exam = grade (percent)

64.8 + 25.2 = 90 (A)
