...teacher salary from $28,000? in 2003–4 by 5% for 2004–5. The school system had a strike in 2004–5 and the salary in 2005–6 was 5% higher than in 2004–5.

What was the percent of increase in salary for beginning teachers from 2003–4 to 2005–6?
 
Let salary in 03/04 = 100
Salary in 04/05 = 100x 0.95 = 95
Salary in 05/06 = 95x 1.05 = 99.75
Salary increase from 03/04 to 05/06 = 99.75 - 100 = - 0.25%

This is a good question. As you see losing 5% first and then gaining 5% does not get you back to where you were!
