Kelly is playing a computer game to help her learn about science. Her scores for the first six games were 10, 12, 10, 8, 14, and 15.

How many points does she need to earn on the next game so that her average score for all games is 12 points?

3


11.5


15


84

Answer 1

the correct answer is 15

I hope this help

Answer 2

To get an average score of 12 she needs a total score for the 7 games to be
7 * 12 = 84 points.

So the score she needs in the next game is 84 - (10+12+10+8+14+15) = 84-69 = 15 points

Answer is 15 points.
