Question

Last year 225 students attended the annual school dance at CCMS. This year 211 students attended the dance. Find the percent of decrease.

Answer 1

Percent of decrease is 17.25%

Step-by-step explanation:

Number of students attended Annual school dance last year = 255 students

Number of students attended Annual school dance this year = 211 students

We need to find percent of decrease.

Decrease = original value - present value

We have,

Original value = 255 students

Present value = 211 students

Decrease = 255-211 = 44

Now, percent of decrease will be;

Percent of decrease =Decrease/original value *100

Percent of decrease = 44/255*100

Percent of decrease =17.25%

So, Percent of decrease is 17.25%

Answer 2

Answer:

17.25%.

Step-by-step explanation:

We have been given that last ear 225 students attended the annual school dance at CCMS. This year 211 students attended the dance. We are asked to find the percent of decrease.

We will use percent decrease formula to solve our given problem as:

$\text{Percent decrease}=\frac{|\text{Final - Original}|}{\text{Original}}\times 100\%$

$\text{Percent decrease}=\frac{|211-255|}{255}\times 100\%$

$\text{Percent decrease}=\frac{|-44|}{255}\times 100\%$

$\text{Percent decrease}=\frac{44}{255}\times 100\%$

$\text{Percent decrease}=0.1725490\times 100\%$

$\text{Percent decrease}=17.25490\%$

$\text{Percent decrease}\approx 17.25\%$

Therefore, percent decrease is approximately 17.25%.
