Respuesta :

30 is correct because 
2   4     6    8    10   12 
5  10  15   20   25  30
The top is counting by 2's and bottom by 5's
Yes, its 30 because is you skip count by 2's on the leaves you move twice to get to 12.
If you skip count by 5's count twice to get to the 12 leaves.
Which is 30 Petals
