Question 894073
{{{(55*(0.85)+35(n))=90}}}, which shows no contribution from participation.
The unit for left and right members is percent of course.
Test 1 and test 2 scores are in decimal fraction form, not as percents.


{{{35n=90-55(0.85)}}}
{{{n=(90-55(0.85))/35}}}
n=.... this will not work.


Best to allow for full "participation".
{{{55(0.85)+10+35*n=90}}}
{{{n=(90-10-55(0.85))/35}}}
{{{n=0.95}}}
This means test 2 score needs to be 95%, and this is with full score part in participation.
