The answer is 15 I’m pretty sure
There would be 2034 students competing in 2012.
We can write a simple equation to find this answer. Let X, be the number of students starting in 2012. Then, we multiply by 0.9 and 1.1 to get to 2014. To work backwards, just divide by 1.1, then by 0.9.
2014 / 1.1 / 0.9 = 2034
That would be B) 25% off. Hope this helps!
Answer:
Square root of {(-2-8)^2+ (-5-1)^2}
Square root of {(-10)^2 + (-6)^2}
Square root of 100 +36
Square root of 136 = 11.66
Distance is 11.66
