You can put this solution on YOUR website!
Note that 50% + 25% + 25% = 100%. This is sometimes called weighting factors. For example your grade on the final carries the most weight of 50% so you want to do the best you can on it. However, even if you got 100% on your final, it only contributes 50 points to your overall grades.
\n" ); document.write( "Here how it works.
\n" ); document.write( "Let FG = your final class grade
\n" ); document.write( "Let FT = your grade on your final test
\n" ); document.write( "Let PG = your grade on the projet
\n" ); document.write( "Let OP = your grade on other projects
\n" ); document.write( "Then
\n" ); document.write( "(1) FG = 50%*(FT) + 25%*(FG) + 25%*(OP)
\n" ); document.write( "Now put in the grades you recieved into (1) and get
\n" ); document.write( "(2) FG = 0.5*(67/100) + 0.25*(90/100) + 0.25*(42/50) or
\n" ); document.write( "(3) FG = 0.5*0.67 + 0.25*0.90 + 0.25*0.84 or
\n" ); document.write( "(4) FG = 0.335 + 0.225 + 0.21 or
\n" ); document.write( "(5) FG = 0.77 or
\n" ); document.write( "(6) FG = 77%
\n" ); document.write( "Answer: Your final class grade is 77%.
\n" ); document.write( "
\n" );
