Answer
Explanation:
Step1: Convert weights to decimals
The weights are $15% = 0.15$, $5%=0.05$, $5% = 0.05$, $75%=0.75$.
Step2: Calculate the product for each category
For Tests: $53\times0.15 = 7.95$. For Labs: $62\times0.05=3.1$. For Assignments: $60\times0.05 = 3$. For Final Exam: $82\times0.75=61.5$.
Step3: Sum up the products
$7.95 + 3.1+3 + 61.5=75.55$.
Answer:
$75.55$
