Algebra.Com's Answer #460612 by DrBeeee(684)![]() ![]() ![]() 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( " |
