Question 706584
my mark right now is a 78 % average. and exams are coming and the exams weight factor is about 15 % of my final mark.
 so if i get about a 55 % on my exam, what would my final mark be?
:
Write this as if there are 100 marks including the exam
av = {{{(85(78)+ 15(55))/100}}}
av = {{{(6630+825)/100}}}
av = {{{7455/100}}} 
ave = 74.55% if you get a 55 on the exam
:
what would my final mark be if i got 80%???
do this exactly the same way, replace 55 with 80
