Question

Last year the Economics Club had 7 members. This year there are 11 members in the club. Estimate the percent change in the number of club members.

Answer 1

First, we have to divide.

`(11)/(7)=1.57`

1.57 represents 157%, which means 11 represents 157% of 7, which is 57 units greater than 100%.

Hence,t the percentage of change is 57%, approximately.
