Each year the Oakland School District publishes its annual budget, which includes information on the sports program's per-student spending. According to the table, what was the rate of change between 2010 and 2011?
Year | Per-student budget
2010 | $34
2011 | $36
2012 | $31
2013 | $28
2014 | $26
Plug the numbers into the formula for rate of change and simplify.
Rate of change
 = \frac{change in value}{change in time}
 = \frac{$36 - $34}{2011 - 2010}
 = \frac{$36 - $34}{1 year}
 = \frac{$2}{1 year}
 = $2 per year
The rate of change between 2010 and 2011 was $2 per year.
