Priscilla's weighted average grade in her Calculus course is 77.5%.
<h3>Calculating weighted average</h3>
In order to determine the weighted average, you will multiply each contributor by its individual weight and then take the sum as shown:
Weighted average = 0.50(87%) +0.30(100%) +0.20(20%)
Weighted average = 43.5% +30% +4%
Weighted average = 77.5%
Therefore Priscilla's weighted average grade in her Calculus course is 77.5%.
