<PRE><B>Question 690912</B>
 if i need a 92% on my final and my final is worth 40% and by getting a 92% i get an 80% in the final course mark.
 what is my avg. sitting at right now?
:
Let x = the present average
:
{{{(6x + 4(92))/10}}} = 80
6x + 368 = 10(80)
6x = 800 - 368
6x = 432
x = (432/6}
x = 72 is your present average</PRE>
