Sofi is competing in a long jump competition. His first jump is 5.25 m. Your best jump is 8% more than this. However, his best jump is 10% lower than the winning jump. Calculate the length of the winning jump.

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.

the answer is. -82562234434584

step-by-step explanation:

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
