Chelsea had made six of seventeen free-throw attempts. How many consecutive free throws must she make to raise her percentage of free throws made to exactly 50 percent?

  • Math -

    (6+x)/(17+x) = 1/2
    12 + 2x = 17+x
    x = 5

    check:
    with 5 more successful throws she made 11 good ones
    out of a total of 17+5 or 22
    11/22 is 50%
