Okay... they are giving you a lot of information. your job is to #1 sort/identify and #2 solve! #1 sort/Identify: There were 24 boys and 20 girls. (In the back of your mind keep the total number - 44) Boys increased by 25% and girls decreased by 10%. #2 solve: What is 25% of the  boys ? Answer: 6 What is 10% of the  girls? Answer: 2 So, if the boys increased by 25% add- 24 + 6 = 30 And, if the girls decreased by 10% subtract- 20 - 2 = 18 Q: Was there an increase or decrease in overall membership? Original total: 44 New Total: 48 Answer: there was an increase overall. Make sense?
