A. 20
B 16 2/3
C. 25
D. 200
E. 2
My answer is 1200-1000=200
200/1200= 1/6 ( some wrong )
Right.
To find the percent, multiply:
0.1666666 * 100 = 16 2/3%
You need to find the decimal answer. Use a calculator.
the decimal answer is 0.1666666
oh, I get it now, thank you
Yay! :-)
You're welcome.
To find the percent decrease, you need to calculate the decrease in enrollment as a percentage of the original enrollment.
First, calculate the decrease in enrollment by subtracting the final enrollment (1000) from the initial enrollment (1200):
1200 - 1000 = 200
Next, divide the decrease (200) by the original enrollment (1200) and multiply by 100 to get the percentage decrease:
(200 / 1200) * 100 = 16.67
So the percent decrease in enrollment over the three-year period is approximately 16.67%.
Therefore, the correct answer is B) 16 2/3.
