Of 200 students surveyed about their extracurricular activities, some are members of the student council. Of those students on the student council, 85 students also play a sport, and the remaining 72 students do not play a sport. Write an equation to find the number of students who are not on student council.

200 - x = y ; when y is not student council and x is student council

or 200 - 157 = 43

Step-by-step explanation:

I. The only clues we got here are total students is 200, student council and not student counsin.

  - 85 kids of student council play sport.

  - 72 kids of student council not play sport.

So the total of student counsin is

   = 85 + 72

 x  = 157

II. Find the kids who are not student council

When total student - student council = not student council

           200 - x = y

           200 - 157 = 43

So  y  = 43

That makes 43 kids of students who aren't student council.

Hope that help :)

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
