Explanation:

Step1: Convert weights to decimals

$27\% = 0.27$, $8\%=0.08$, $14\% = 0.14$, $51\%=0.51$

Step2: Calculate weighted - grade for each category

Tests: $88\times0.27 = 23.76$
Labs: $41\times0.08 = 3.28$
Assignments: $93\times0.14 = 13.02$
Final Exam: $80\times0.51 = 40.8$

Step3: Sum up the weighted - grades

$23.76+3.28 + 13.02+40.8=80.86$

Answer:

$80.86$
