Solution:
The allyl cation unit (CH⁺-CH=CH) gives 2 forms, and each can be drawn with 2 Kekule forms of the benzene ring : 4 structures.
In the form where + is on the carbon attached to the benzene ring (benzylic), the charge goes to the 2 ortho and 1 para ring carbons : 3 more structures.
Total = 4 + 3 = 7.
