Question

Last year there were 29 students at a creative writing workshop. This year 35 students attended the workshop. To the nearest tenth, what is the percent of change in the number of students in attendance?

Answer 1

Divide 100 by 29. You get 3.45.
Subtract 35 by 29 and you get 6.
6 times 3.45 equals 20.7.
Answer:20.7

Answer 2

Answer:

The  percent of change in the number of students in attendance is:

                            20.7%

Step-by-step explanation:

Last year there were 29 students at a creative writing workshop.

This year 35 students attended the workshop.

The percent change in the number of students in attendance is:

$\text{Percent change}=\dfrac{|\text{Number of students this year-Number of student last year}|}{\text{Number of student last year}}\times 100$

Hence,

$\text{Percent change}=\dfrac{|35-29|}{29}\times 100\\\\\\\text{Percent change}=\dfrac{6}{29}\times 100\\\\\\\text{Percent change}=20.689\%$

which to the nearest tenth is:

$\text{Percent change}=20.7\%$
