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 = %2885%2878%29%2B+15%2855%29%29%2F100
av = %286630%2B825%29%2F100
av = 7455%2F100
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
