The monthly enrollment at a preschool decreased by 8% during one month and increased by 6% during the next month. What was the cumulative percent change for the two months?
选项
答案
2.48%
解析
If E is the enrollment before the first month, then the enrollment as a result of the 8% decrease can be found by multiplying the base E by the decimal equivalent of 100% - 8% = 92%, which is 0.92:
0.92E
The enrollment as a result of the second percent change—the 6% increase—can be found by multiplying the new base 0.92E by the decimal equivalent of 100% + 6% = 106%, which is 1.06:
(1.06)(0.92)E = 0.9752E
The percent equivalent of 0.9752 is 97.52%, which is 2.48% less than 100%. Thus, the cumulative percent change in the enrollment for the two months is a 2.48% decrease.
