Question 26
At the science fair of a school, it was observed that half of the elementary school students and a quarter of the high school students present at this event bought a sticker each.
| Science fair | |
| :---: | :---: |
| sticker price (unit) | |
| $R\$ 0,30$ | elementary school students |
| $R\$ 0,50$ | high school students |
It was also noted that the number of high school students present who did not buy stickers was double the number of elementary school students who did not buy stickers. Knowing that $R\$ 38,00$ was collected in the sale of stickers for students at these two levels, how many students from each level participated in the fair?
