Suppose, the percentage of increase is
![x\%](https://img.qammunity.org/2019/formulas/mathematics/high-school/vaj2392okg0n7z410xo3wbgf4732ru4s67.png)
So, the amount of increase =
of 1480
![=1480*(x)/(100)=14.8x](https://img.qammunity.org/2019/formulas/mathematics/high-school/6j3j06hfs47de16tp3u07wnv60bocik8h8.png)
Thus, the equation will be......
![14.8x= 2768-1480\\ \\ 14.8x=1288\\ \\ x= (1288)/(14.8)=87.027....](https://img.qammunity.org/2019/formulas/mathematics/high-school/9apyi9wsjm8gxhcdslceu4zcpjz4cfri9p.png)
So, the percentage of increase was 87.027... %
