In order to achieve an average of 12 successful shots she has to score 36 times in total. So, she has to score 5 times in the 3rd set.

13 + 18 + 5 = 36

In order to achieve an average of 16 successful shots she has to score 48 times in total. So, she has to score 17 times in the 3rd set.

13 + 18 + 17 = 48

Express your answer in the form of a compound inequality using the variable F to represent a successful basketball free throw:

5 < = F < = 17
