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%.

Answer:
280
Step-by-step explanation:
We know that there are at least 8 regular subscribers and there are at least 9 premium subscribers. And we know it's in that ratio. So the best way to start this is to divide 595 by 8+9 to get the single unit amount of both subscribers:
595/17 = 35
So one unit of anything is at least 35. Now, since we're looking for regular subscribers, we'll multiply this value by 8:
35*8 = 280
So 280 is our answer!
