Your final grade is composed of 3 parts, 20% from the first question, 20% from the second question and 60% from the final exam score. 20% of 69% is \[0.20 \times 69\%\] 20% of 68% is \[0.20 \times 68\%.\] and 60% of S% is \[0.6 \times S\%.\] Your final grade was 63% and hence \[0.20 \times 69\% + 0.20 \times 68\% + 0.6 \times S\% = 63\%.\] Solve for S.
