The percentage change can be calculated with the following formula:
![Percentage\ change=(New\ value-Old\ value)/(Old\ value)*100](https://img.qammunity.org/2020/formulas/mathematics/middle-school/reclg2atn3rutv32pes3vbs02bm6w50w6b.png)
In this case you can see in the table provided that:
![New\ value=37.54\\\\Old\ value=28.69](https://img.qammunity.org/2020/formulas/mathematics/middle-school/aghetqvt8sp5xxj7dkqahtkhb4tj3uch3l.png)
Therefore, you need to substitute these values into the formula in order to calculate the percentage change in the stock price of the company from January 2015 to December 2015:
![Percentage\ change=(37.54-28.69)/(28.69)*100\\\\Percentage\ change=30.85\%](https://img.qammunity.org/2020/formulas/mathematics/middle-school/kayr6hrqdlwjvm4xecrjmmmona1wwdw8kf.png)
