Hello Jiaqi,


We've added files with  the solutions to the HW assignments in the class site. Each file contains both the answer and a  detailed solution to each of the problems assigned for HW.


Please take a look at the files and let us know if you still have any questions on those problems,

To answer the original problem: the price increase is $1.32-1.10=0.22$.  This amount is $20\%$ of the original price $1.10$ ($0.22\div 1.10 = 0.2 = 20\%$), therefore it is a $20\%$ increase.
