    Answer: 6.3 m

    Step-by-step explanation:

    "8% more" = 1.08 (which is 1+0.08). "10% less" = 0.90 (which is 1-0.10).

    first = 5.25

    her_best = 1.08*first

    her_best = 0.90*winning

    Substitute to determine the winning jump's length.

    winning = 1.08*5.25/0.90 = 6.3

    So, the winning jump was 6.3 meters.
