Question

Given that John's bowling scores were 120, 144, 143, 111 and 167, find his average score. (The rule for calculating the average of a set of scores is: Average Score = Sum of Scores/Number of Scores.)

Answer 1

Answer: 137

Explanation:

1. Add 120+144+143+111+167

2. Divide the result of that by 5, because there are 5 numbers.

3. The average is 137

Answer 2

Rule for calculating the average of a set of scores is:
Average Score = Sum of Scores/Number of Scores
Sum of scores = 120 + 144 + 143 + 111 + 167 = 685
Number of scores = 5
Average Score = 685/5 = 137
Thus his average score is 137.
