Sarah competes in a long jump competition her first jump is 4.25m her best jump is 12% more than this however, her best jump is 15% lower than the winning jump work out the length of the winning jump

So her best jump is 12% of her 1st jump. So this is:

best jump = 1.12 * 4.25 m

best jump = 4.76 m

Since the winning jump is 15% lower, so this is only 85% of the best jump hence:

winning jump = 0.85 * 4.76 m

winning jump = 4.046 m = 4.05 m

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
