How do i figure out my semester grade?

Question

final exam is worth 15% and i got a 74%

then for third marking peroid i got a 43.1

and fourth i got 58.1 how do i figure out my semester grade

Answer 1

You find your average by 43.1 times 58.1 then divide by two. Once you have that answer, times 74 by .25. then you times that to your original answer and divide by two again....i THINK
