Answer:
uhhh the question isn't clear but if she wants to give each friend 1 she'll need 8 chocolate bars. If she wants to give each friend 2 she'll need 16 and so on, I'll provide a multiplication table of 8.
8 x 1 = 8
8 x 2 = 16
8 x 3 = 24
8 x 4 = 32
8 x 5 = 40
8 x 6 = 48
8 x 7 = 56
8 x 8 = 64
8 x 9 = 72
8 x 10 = 80
8 x 11 = 88
8 x 12 = 96
