Question 157479: I need help with this problem
Solve the problem: Clearwater Community College has 1242 students enrolled in 1998 and 980 students enrolled in 1999. Find the percent of decrease in the number of students from 1998 to 1999. Round to the nearest tenth of a percent.
Answer by gonzo(654) (Show Source): You can put this solution on YOUR website!
number of students in 1998 is 1242.
number of students in 1999 is 980.
percent increase / decrease from 1998 to 1999 is ((number of students in 1999 minus number of students in 1998) divided by number of students in 1998) * 100%.
this becomes (980-1242)/1242)*100%
this becomes (-262/1242)*100%
this becomes -.210950081*100%
this becomes -21.09500805%
rounded to nearest 10th of a percent, this becomes -21.1%
