Question

12.

In his first three years coaching baseball at High Ridge
High School, Coach Batty's team won 7 games the first
year, 16 games the second year, and 4 games the third
year. How many games does the team need to win in
the fourth year so that the coach's average will be 10
wins per year?
(A) 13
(B) 10
C) 9
(D) 3

Answer 1

The answer is A

Explanation:

In order to find average you add all the values and divide the total by the total number of values. In this particular situation if you add 7 + 16 +4 + 13 you get 40 and if you divide that by the total number of data values, 4 you get 10 which means the only correct answer choice is A.
