The goal of the amusement park is to appeal to people between the ages of 13 and 25. So far, the people who have bought tickets are 10, 10, 15, 29, and 32. What age does the next person need to be in order to maintain the target age group?
+118608 I am not sure what this question means 
$${\frac{\left({\mathtt{10}}{\mathtt{\,\small\textbf+\,}}{\mathtt{10}}{\mathtt{\,\small\textbf+\,}}{\mathtt{15}}{\mathtt{\,\small\textbf+\,}}{\mathtt{29}}{\mathtt{\,\small\textbf+\,}}{\mathtt{32}}\right)}{{\mathtt{5}}}} = {\frac{{\mathtt{96}}}{{\mathtt{5}}}} = {\mathtt{19.2}}$$
At the moment the average age is 19.2 years
Maybe it means that the average has to be between 13 and 25
$$\\13<\frac{96+X}{6}<25\\\\
78<96+X<150\\\\
0
But really the person should be between 13 AND 25
I think that this is a dumb question
