We can let n = the number of balloons Kenny has.

Statement One Alone:

If Kenny had 3 fewer balloons, he would have only half as many as he actually has.

We can create the following equation:

n - 3 = (1/2)n

2n - 6 = n

n = 6

Statement one alone is sufficient to answer the question.

Statement Two Alone:

Kenny has twice as many blue balloons as red balloons.

The information in statement two does not tell us how many balloons Kenny has.

Answer: A
