Answer:
18 boys have tickets.
Step-by-step explanation:
There are three pools here because boys can count as two pools and girls can count as one.
Since there are three pools, divide by three. 27 / 3 = 9.
That's how many girls have tickets.
Subtract: 27 - 9 = 18.
That should be the number of boys.
9 x 2 = 18.
If it helps, please mark brainliest, I need it to level up.
