In 2000, the number of students enrolled at Arlington Country Day School was 823 students. In 2010, the population was approximately 705 students. Find the percent of change in the enrolled students at Arlington Country Day school from 2000 to 2010 and identify it as an increase or decrease.
A. 14.3%; increase
B. 14.3%; decrease
C. 16.7%; increase
D. 16.7%; decrease
All I know is it's either B or D, but I'm not sure which one.
clearly it was a decrease. The % change is
(705-823)/823 = -14.3%
Thanks!
Well, look at you, narrowing it down to just two choices! That's impressive. Now, let me help you solve this math puzzle with a touch of humor.
To find the percent of change, we can use the formula: ((final value - initial value) / initial value) x 100.
Let's plug in the numbers: ((705 - 823) / 823) x 100 = (-118 / 823) x 100
Doing the math, we get approximately -14.34%.
So, the percent change is around -14.34%.
Does that match any of the options? Ah, there it is! The correct answer is B. 14.3%; decrease.
Well done, my friend! You've cracked the code. Keep up the good work!
To find the percent of change in the enrolled students at Arlington Country Day School from 2000 to 2010, we need to calculate the percentage decrease. To do this, we'll use the following formula:
Percent Change = ((New Value - Old Value) / Old Value) * 100
Given:
Old Value (2000) = 823 students
New Value (2010) = 705 students
Percent Change = ((705 - 823) / 823) * 100
Percent Change = (-118 / 823) * 100
Percent Change ≈ -0.143 * 100
Percent Change ≈ -14.3
Since the percentage change is negative, the correct answer is:
B. 14.3%; decrease
To find the percent of change in the number of enrolled students at Arlington Country Day School from 2000 to 2010, you will need to use the formula:
Percent Change = (Difference / Original) * 100
First, calculate the difference in the number of enrolled students:
Difference = Final - Initial
In this case:
Final = 705 (number of students in 2010)
Initial = 823 (number of students in 2000)
Difference = 705 - 823 = -118
Next, plug in the values into the formula:
Percent Change = (-118 / 823) * 100
Now, calculate the value:
Percent Change = -14.34... (rounded to two decimal places)
Since the result is negative, it indicates a decrease in the number of enrolled students. The correct option is:
B. 14.3%; decrease
