The following data set represents the enrollment since the fall of 1980. Let x be the number of years since 1980.
YEAR x 1980 1981 1982 1983 1984 1985 1986 1987 1988 1999
ENROLLMENT y 1414 1454 1439 1555 1617 1727 1717 1804 1833 1881
YEAR x 1990 1991 1992 1993 1994 1995 1996 1997 1998
ENROLLMENT y 1965 2176 2449 2679 2885 2999 3124 3301 3503
Compare the enrollment for each year to the previous year and find the percent increase/decrease in enrollment. Round to the nearest hundredth.
+130514 Whoa, dude...are you kidding???....that would take us all night!!!
I'll tell you how to do it.....and then.......good luck...!!!
Percent Increase/ Decrease =
(Subsequent Year - Previous Year) / Previous Year x 100 %
For instance from 1980 to 1981 we have
[1454 - 1414]/ 1414 x 100% =
[40 / 1414] x 100% =
about 2.83% {rounded to the nearest hundredth }
P.S. - If you know how to use a speadsheet program like Excel...it would be a simple matter to calculate these answers......that's probably what I would suggest......!!!....very lengthy, otherwise......
