Question

George is entering a speaking contest where he is judged on three topics. Content is worth 50%, appearance is worth 25% and delivery is worth 25% of his total score. What is his weighted score, rounded to the nearest percent, if he earned an 87% on content, 90% on appearance and 85 on delivery

Answer 1

To calculate George's weighted score, we need to first find the weighted value of each topic.

Content: 87% x 0.50 = 43.5%

Appearance: 90% x 0.25 = 22.5%

Delivery: 85% x 0.25 = 21.25%

Now we can find his total weighted score by adding the weighted values together:

43.5% + 22.5% + 21.25% = 87.25%

So George's weighted score, rounded to the nearest percent, is 87%.
