I believe 8.30%..........
rate of blowing balloons of Alexa = 15/20 = 0.75
rate of blowing balloons of Sara = 18/25 = 0.72
rate of blowing balloons of Shirley= 16/21 = 0.76
rate of blowing balloons of Sam = 12/23 = 0.52
from above calculation we concluded Shirley can blow balloons at the fastest rate!
So the answer is <span>–1.8 +0.9 –1.4 +0.4
or C. -1.9</span>
3144/9= 349.33
I used a calculator, but you can also solve this by long division (if a calculator isn’t available)
hope this helps!! :)
