Question

Sam scored 59, 64, and 68 points on three tests. how many points should he get on the fourth test to get an average score of 70? 63.67 points 65.25 points 75 points 89 points

Answer 1

s (score) = 89

Explanation:

We find the average (or mean) by dividing the sum of the data points by the total number of points (4 in this problem)

With s representing the final score needs to get an average score of 70, we have (59 + 64 + 68 + s) / 4 = 70

191 + s = 280

s = 89
