Question 1038685
<font face="Times New Roman" size="+2">


Number of times last year: *[tex \Large t]


Number of times this year: *[tex \Large 21\ -\ t]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{t}{2}\ >\ 21\ -\ t]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{3t}{2}\ >\ 21]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ t\ >\ 14]


But the most number of times that she could have gone last year was 21 (if she didn't actually go at all this year), so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 14\ <\ t\ \leq\ 21]

My calculator said it, I believe it, that settles it
