Option Analysis
Statement I is insufficient: Sally gave each friend 8 pieces of candy. Clearly insufficient.
Statement II is insufficient: Sally had 7 pieces of candy left after giving candy to her friends. Also insufficient.
Together I and II, If Sally gave candy to 2 of her friends, then she had 7+2*8=22 pieces of candy but if she gave candy to 3 of her friends, then she had 7+3*8=31 pieces of candy. Not sufficient.
