Formula to calulate the weighted average
I _think_ your instructor wants this formula in F17:
=$c$8*b17 + $c$9*c17 + $c$10*d17 + $c$11*d18
The $'s means that these cells won't change if you copy the formula to other
cells--like in F18, F19, ..., F9999.
Another formula that may get you into trouble:
=SUMPRODUCT($C$8:$C$11,TRANSPOSE(B17:E17))
This is an array formula. Hit ctrl-shift-enter instead of enter. If you do it
correctly, excel will wrap curly brackets {} around your formula. (don't type
them yourself.)

I need some help on a spreadsheet I am working on. I am suppose to use
absolute cell references to calculate the overall total for four exams by
using the four weights found in a different cell range. As follows:
Exam 1 weight 20% cell C/8
Exam 2 weight 20% cell C/9
Exam 3 weight 20% cell C/10
Final Exam weight40% cell C/11
Cell B/17 Cell C/17 Cell D/17 Cell E/17
Cell F/17
Student I exam I 84.0 exam 2 80.0 exam 3 83.0 exam final exam 72.0 overall
total
It states in Cell F17 enter a formula to calculate the weigted average of
the first student's four exams. Use the weights found in the range C8:C11,
matching each weight with the corresponding exam score. Use absolute cell
references for the four weights....
HELP!!! I have no clue what to do here
