Winona needs to average 5.8 points from 14 judges to win the competition. The mean score of 13 judges was 5.9. What is the lowest score she can receive from the fourteenth judge and still win?

Question

I have no idea. Please help. Thanks

Answer 1

Mean = ∑x/n

5.8 = (13*5.9 + x)/14

Solve for x.
