Question

Jennifers average score and four rounds of the game was 16 points. She scored 18 points in the first round, 12 points in the second round, and 15 points in the third round. How many points did Jennifer score in the fourth round.

Answer 1

19 points

Explanation:

Let's make the fourth round x.

To find the average, we can use the mean. The mean is all the numbers added up then divided by the total amount of numbers.

18 + 12 + 15 + x ÷ 4 = 16

45 + x ÷ 4 = 16

45 + x = 16 × 4

45 + x = 64

x = 64 - 45

x = 19

Jennifer has to score 19 points to have an average (mean) of 16 points.
