Let the number of glue sticks brought in Mrs. Thornton class be 'x'
Let the number of tables brought in Mr. Still class be 'y'
According to the question, the number of tables of Mr.Still class is 3 times as many glue sticks as in Mrs.Thornton class.
Therefore, Number of tables = 3 x Number of glue sticks
So, y = 3
![* x](https://img.qammunity.org/2019/formulas/mathematics/middle-school/y3vou6apkr3yk7egsrmjdlhjw3scj8bf42.png)
![y = 3x](https://img.qammunity.org/2019/formulas/mathematics/middle-school/teh3e8j8bxy4mgdjtfjqfbhb1m7bxubon2.png)
Now, we have to determine the number of glue sticks.
Since,
![y = 3x](https://img.qammunity.org/2019/formulas/mathematics/middle-school/teh3e8j8bxy4mgdjtfjqfbhb1m7bxubon2.png)
Therefore,
![x = (y)/(3)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/g9xwixqay9o8gjvmlu4d0xv73yeno63pnq.png)
So, there are
glue sticks which that table group brought in Mr.Still class.
