Question

Marianne has scored 27, 18, and 28 points in her last three JV Basketball games. How many points must she score in her next game to have a four-game average of greater than 25 points?

Answer 1

She must score more than 27.

27 + 27 + 18 + 28 = 100

100/4 = 25

Answer 2

To have an average of > 25, her total points scored must be > 100. If you need a whole number it has to be 104 or greater.

so far she has 27 + 18 + 28 = 73. An average of 24.33

100 - 73 = 27.

If she gets 27 in her next game she will have an average of 25 so any number > 27 will give her an average of > 25.
