Ⓗⓘ ⓣⓗⓔⓡⓔ

Well, in order to solve these types of problems, you would divide by the percent.

For example {keep in mind this is reduced by 30%, making it 70%}:

17920/70=256

Then we would multiply that by 100 {making it 100%}:

256*100=25,600

And to check, we would multiply the original percentage by the number we just got.

25,600*0.7=17920

So you have your answer, 25,600
