Question

Your scores on the last 3 bowling games are 99,92, and 115. Write and solve an inequality to find the score you need in the next game to have a mean score of at least 100.

Answer 1

Score in 4th game = 94

Explanation:

The mean is the average of all the data points, which means we divide the sum of all the points by the total number of points.

Letting s represent the score in the 4th game, we can use the following equation to find the score needed to end up with a mean score of 100:

`(99+92+115+s)/(4)=100\\ (306+s)/(4)=100\\ 306+s=400\\s=94`
