Answer:
The school's championship record is 5 m
Kaydeen must increase her personal best by 25%
Step-by-step explanation:
Find the school's championship record by dividing 6 by 1.2
6/1.2
= 5
So, the school's championship record is 5 m
Find the percentage that she has to increase her personal best to equal the national record, by finding the percent change
Divide the difference in the scores by Kaydeen's score
1.5/6
= 0.25
So, Kaydeen must increase her personal best by 25%
B and c are correct because you use divison and multiplication to get the right answer and the right answer is 99cm
