77% is worth 70 marks



0.77 X70 = 53.9 marks



88% is worth 30 marks



0.88 X 30 = 26.4 marks



ADD 53.9+ 26.4 = 80.3 % ANSWERHow do i calculate my final percentage?
Your final score would be 80.3%. To calculate, I would use .7 and .3 to represent the "value" of each grade, and then multiply the score by their "value" and the the products to get my answer.



(77 * .7) + (88 * .3)=80.3How do i calculate my final percentage?
The rerst of the course is worth 70% of your grade, so the weighted average is



0.7(77) + 0.3(88) = 80.3%
77*0.7+ 88*0.3=80.3
